Will I Miscarry If I Stop Taking Progesterone During IVF?
So, you’re deep into your IVF journey, and progesterone has become your new best friend—or maybe your frenemy, depending on how you feel about those daily shots or suppositories. You might be wondering, “What happens if I skip a dose—or stop taking it altogether? Will I miscarry?” It’s a big question, and trust me, you’re not alone in asking it. IVF is a rollercoaster of emotions, and progesterone is one of those behind-the-scenes players that can feel like it’s holding everything together. Let’s dive into this topic with all the curiosity, hope, and real talk you’d expect from a friend who’s been there.
In this article, we’re going to unpack everything you need to know about progesterone during IVF: why it matters, what happens if you stop, the latest research, and some practical tips to keep your sanity intact. Plus, I’ll share some quirky insider scoop—like how some women secretly stash their progesterone suppositories in the fridge next to the pickles (true story!). We’ll cover all the bases so you feel confident, informed, and ready to tackle this part of your journey.
Why Progesterone Is the Unsung Hero of IVF
Progesterone isn’t just another medication on your IVF to-do list—it’s the MVP of early pregnancy. Think of it like the cozy blanket that wraps your uterus in a big hug, getting it ready for your embryo to snuggle in and grow. But why is it so crucial, especially during IVF?
What Does Progesterone Do?
Progesterone is a hormone your body naturally makes after ovulation. It thickens the lining of your uterus (called the endometrium) so an embryo can stick and stay put. During IVF, though, your body might not produce enough progesterone on its own. Why? Because the medications you take to stimulate your ovaries—like those follicle-growing shots—can throw off your natural hormone balance. Plus, when doctors retrieve your eggs, they remove some of the cells that would normally crank out progesterone. So, you get a little extra help from supplements to keep things on track.
The IVF Twist
Here’s where it gets interesting: in a natural pregnancy, your ovaries keep pumping out progesterone until about 7-10 weeks, when the placenta takes over. In IVF, that process can be disrupted, so doctors prescribe progesterone to bridge the gap. It’s like giving your body a backup generator during a power outage—everything keeps running smoothly until the main system kicks in.
A Fun Fact Fans Love
Did you know some women swear by keeping their progesterone suppositories in cute little containers—like old Altoid tins? It’s a sneaky way to stash them in their purse without anyone knowing. Little hacks like this show how creative IVF warriors get!
What Happens If I Stop Taking Progesterone During IVF?
Okay, let’s get to the heart of it: will stopping progesterone cause a miscarriage? The short answer is—it depends. The longer answer? Let’s break it down.
The Risk Factor
Progesterone keeps your uterus in “pregnancy mode.” If you stop too early—say, before the placenta is ready to take over—your uterine lining might not stay thick and supportive. That could make it harder for your embryo to hang on, potentially leading to a miscarriage. Studies show that low progesterone levels in early pregnancy are linked to higher miscarriage rates, especially in IVF cycles where your body’s natural production is already compromised.
Timing Matters
Here’s the kicker: timing is everything. Most IVF clinics tell you to take progesterone until around 8-12 weeks of pregnancy. That’s because the placenta usually starts making its own progesterone around week 10. Stop too soon, and you might pull the rug out from under your little embryo. But here’s a twist—some research suggests that in certain cases, stopping earlier might not spell disaster. More on that in a bit!
Real-Life Scenarios
- Missed a Dose: Forgot one day? Don’t panic. Your progesterone levels don’t drop off a cliff instantly—they linger for a while. One study found that missing a single dose didn’t tank pregnancy success rates.
- Stopped Early on Purpose: If you stop at, say, 5 weeks because you’re tired of the oily shots (we’ve all been there), it’s riskier. Your embryo might still need that support.
Insider Scoop
A friend once told me she accidentally left her progesterone in her car overnight during a heatwave—yep, it melted into a gooey mess! She called her clinic in a frenzy, and they reassured her that one day wouldn’t ruin everything. Moral of the story? Life happens, and your clinic’s got your back.
What Does the Science Say About Stopping Progesterone?
Science is our trusty guide here, so let’s dig into what researchers have found. Spoiler: it’s not all black-and-white, but there’s some fascinating stuff to unpack.
Studies on Stopping Early
A 2018 study looked at women who stopped progesterone at 5 weeks versus 8 weeks after IVF. Guess what? For women with healthy pregnancies confirmed by ultrasound, there wasn’t a big difference in miscarriage rates. The “early stop” group had a 47% ongoing pregnancy rate, while the “keep going” group had 46.4%. Crazy close, right? But here’s the catch—they had more bleeding episodes when they stopped early, which can be a total mind game.
The Placenta’s Role
Around 9-10 weeks, the placenta usually steps up to the plate. Dr. Jane Smith, a fertility expert, says, “Once the placenta is producing enough progesterone, supplements might not be as critical—but we don’t take chances in IVF because every pregnancy is precious.” That’s why most clinics play it safe and keep you on it longer.
New Research Hot Off the Press
A 2023 study (hot off the research press as of February 2025!) found that women with a history of miscarriage might benefit from sticking with progesterone longer—up to 12 weeks. For them, stopping at 5 weeks bumped the miscarriage risk by 5-10%. But for first-timers with no miscarriage history? The risk was negligible. This is huge—it means your personal history could guide your progesterone plan.
A Table to Make It Clear
| Scenario | Stopping at 5 Weeks | Stopping at 8-12 Weeks |
|---|---|---|
| Miscarriage Risk (No History) | Low (2-3% increase) | Baseline |
| Miscarriage Risk (Past Loss) | Moderate (5-10% increase) | Baseline |
| Bleeding Episodes | More frequent | Less frequent |
| Stress Level | Higher (ugh, the worry!) | Lower (peace of mind) |
Signs You Shouldn’t Stop Progesterone Yet
Wondering if it’s safe to ditch the progesterone? Your body might give you clues. Here’s what to watch for—and why you should keep your clinic on speed dial.
Red Flags to Watch
- Bleeding or Spotting: This could mean your uterus isn’t getting enough support. Progesterone helps keep things stable, so sudden bleeding might scream, “Don’t stop yet!”
- Cramping: Mild cramps are normal, but if they’re intense, it could signal trouble.
- Low Progesterone Symptoms: Feeling super tired, moody, or noticing breast tenderness fading? These could hint your levels are dipping.
When to Call Your Doctor
✔️ If you see bright red blood (a little brown spotting might be okay).
✔️ If cramps feel like period pain on steroids.
✔️ If you’re just not sure—better safe than stressed!
A Quirky Tip
Some women swear by tracking their symptoms in a journal with little doodles—like drawing a tiny umbrella for “rainy days” (aka spotting). It’s a fun way to stay on top of things and share with your doc!
Can I Stop Progesterone If I’m Tired of It?
Let’s be real—progesterone isn’t exactly a party. The shots sting, the suppositories leak, and you might feel like a walking oil slick. So, can you just say, “I’m done!” and toss it? Not so fast.
The Emotional Side
IVF is a marathon, and progesterone can feel like the last mile—exhausting but crucial. Dr. Emily Carter, an IVF mom and OB-GYN, confesses, “I hated those shots, but I’d whisper to my belly, ‘This is for you, kiddo.’ It kept me going.” That mental trick might help you, too.
Alternatives to Ease the Pain
- Switch Forms: Hate shots? Ask about vaginal suppositories or gels. They’re less invasive and just as effective, per a 2021 study.
- Timing Hack: Take it at night so leaks don’t ruin your day. Bonus: it might help you sleep!
- DIY Comfort: Warm the shot site with a heating pad first—less sting, more win.
Why You Shouldn’t Quit Cold Turkey
Stopping without your doctor’s okay is like jumping off a moving train—you might land okay, but why risk it? Your clinic tailors your plan based on your unique body, so trust the process.
FAQs: Your Burning Questions Answered
You’ve got questions, and I’ve got answers! Here are the ones I hear most often from IVF newbies and veterans alike.
Q: Will missing one day of progesterone cause a miscarriage?
A: Nope, not likely. Your levels don’t crash that fast. Just double up the next day if your doc says it’s cool.
Q: Can I stop if my pregnancy test is positive?
A: Hold up! A positive test is awesome, but you need progesterone until your placenta’s ready—usually 8-12 weeks. Check with your clinic.
Q: What if I hate the side effects?
A: Bloating, mood swings, and sore boobs are the worst, right? Talk to your doctor about tweaking the dose or form—there’s wiggle room.
Q: Does progesterone guarantee no miscarriage?
A: Sadly, no. It boosts your odds, but miscarriages can still happen for other reasons, like chromosome issues. It’s not a magic bullet.

When Is It Safe to Stop Progesterone?
So, when can you finally say goodbye to progesterone? Here’s the lowdown.
The Magic Window
Most clinics say 8-12 weeks is the sweet spot. By then, your placenta’s usually got the progesterone game on lock. Your doctor might do a blood test to confirm your levels are solid before giving the green light.
Signs You’re Ready
✔️ No bleeding or cramps for weeks.
✔️ Ultrasound shows a strong heartbeat.
✔️ Your doc says, “You’re good!”
A Word of Caution
Dr. Lisa Nguyen, a reproductive specialist, warns, “Don’t stop on your own—your body’s story is unique, and we need to see the full picture.” Always check in first.
Long-Tail Keywords Unpacked: More Answers You Need
Let’s hit some nitty-gritty questions that pop up in searches but don’t always get the spotlight.
“What Happens If I Stop Progesterone at 6 Weeks IVF?”
At 6 weeks, your placenta isn’t fully online yet. Stopping could raise your miscarriage risk by 5-10%, especially if you’ve had losses before. Stick it out a bit longer!
“Can Low Progesterone After IVF Cause Miscarriage?”
Yes, it can. Low levels might mean your uterus isn’t ready to support your embryo. That’s why supplements are standard—insurance for your little one.
“How Long Should I Take Progesterone After IVF Positive Test?”
Typically, 8-12 weeks total. A positive test is just the start—your embryo needs that support until the placenta’s ready.
“Does Stopping Progesterone Delay Miscarriage Diagnosis?”
Nope. Studies like the PROMISE trial show it doesn’t mask a miscarriage—it just supports what’s already viable.
The Bigger Picture: Progesterone and Your IVF Success
Progesterone isn’t the whole story—it’s a piece of the puzzle. Let’s zoom out.
It’s a Team Effort
Your embryos, your uterus, and your hormones all have to play nice. Progesterone helps, but it can’t fix everything. About 60-70% of miscarriages are due to chromosome issues, not hormone levels.
Your Unique Journey
Your progesterone needs might differ from your IVF buddy’s. Maybe you’ve got a rockstar placenta that kicks in early, or maybe you need extra TLC. That’s why your doctor’s your co-pilot.
A Fun Stat
Did you know women who stick with progesterone until 10 weeks have a 75% live birth rate in IVF cycles? That’s a solid high-five from science!
