Bleeding during early pregnancy is scary. For many, it triggers panic and worst-case-scenario thinking — and understandably so. One minute, everything seems fine. The next, there’s blood. But while bleeding in pregnancy should always be checked out, it doesn’t always mean miscarriage. In fact, it’s sometimes diagnosed as something called a threatened miscarriage — which, despite the name, doesn’t mean miscarriage is certain.
Let’s break it down: what a threatened miscarriage actually means, how common it is, what to do (and what not to do), and when to seek help.
What does “threatened miscarriage” mean?
Threatened miscarriage is a medical term that’s typically used when someone experiences vaginal bleeding during the first 20 weeks of pregnancy — but their cervix is still closed and there’s evidence the pregnancy is continuing (like a fetal heartbeat on an ultrasound).
In other words, something might be going on that could lead to a miscarriage, but it hasn’t happened — and may not happen.
According to recent studies, around 20-25% of all pregnancies will have some bleeding in early pregnancy, and of those, in pregnancies with a heartbeat, 89% don’t result in a miscarriage. That means a threatened miscarriage doesn’t guarantee a loss — and many people go on to have healthy pregnancies afterward.
Common signs of a threatened miscarriage include:
- Vaginal bleeding (light spotting to heavier bleeding)
- Mild cramping or lower back pain
- A feeling of pelvic pressure
If you’re experiencing any of these symptoms, always check in with your OB-GYN or midwife. A simple scan or exam can help clarify what’s going on.
Is a threatened miscarriage an inevitable miscarriage?
No — and that’s a crucial distinction. A threatened miscarriage means there’s a risk, not a certainty.
Research shows that about half of people with a threatened miscarriage go on to have a healthy pregnancy. The odds may be even better if there’s a strong fetal heartbeat on the scan and no other risk factors present.
Factors that might increase the chance of progressing to miscarriage include:
- Heavier bleeding or passing clots
- No fetal heartbeat detected
- Abnormally shaped uterus or certain uterine conditions
- Chromosomal abnormalities
- Maternal infections or hormone imbalances

Still, many people with mild bleeding go on to carry to term. Every pregnancy is different, and that’s why monitoring and follow-up care are key.
What not to do when you have a threatened miscarriage
Finding out you have a threatened miscarriage can be emotionally overwhelming. And naturally, the instinct is to do something — anything — to stop it. But while there are a few supportive measures that may help, there are also some things it’s best to avoid. Here's what not to do:
- Don’t panic-Google. Easier said than done, but remember: not everything you read online will be accurate or relevant to your case. Stick to reputable sources (like Tommy’s, the Cleveland Clinic, or your healthcare provider).
- Don’t ignore symptoms. Even if you think it’s “just spotting,” it’s always best to get checked out.
- Don’t self-medicate. Some herbs and over-the-counter supplements marketed for miscarriage prevention aren’t safe in pregnancy. Always talk to your provider before taking anything new.
- Don’t blame yourself. There is nothing you did to cause this. Threatened miscarriages can happen for many reasons, most of which are out of anyone’s control.
- Don’t isolate. You deserve support. Whether it’s a partner, friend, therapist, or online community — you’re not alone in this.
How to save a threatened miscarriage
This is the question everyone asks — and unfortunately, there’s no magic fix or guaranteed treatment. But there are things that may help support your body and increase your chances of continuing the pregnancy, depending on what’s causing the symptoms.
Your healthcare provider might:
- Recommend rest (especially pelvic rest, meaning no sex or heavy lifting)
- Prescribe progesterone, particularly if hormone levels are low
- Monitor with ultrasounds to track fetal development and bleeding
- Run tests to check for infections, thyroid issues, or other treatable conditions
In some countries, progesterone supplements are offered to those with recurrent miscarriage or low progesterone levels. A major clinical trial in the UK, the PRISM study, found that progesterone treatment may help people with early pregnancy bleeding who have had previous losses, but it’s not a necessarily universal solution.
Should I rest if I have a threatened miscarriage?
Bed rest used to be a go-to recommendation — but recent research suggests it may not make a significant difference in preventing miscarriage, and too much rest can come with downsides like muscle loss and increased stress. That said, taking it easy (reducing strenuous activity, avoiding sex if advised, and listening to your body) is usually a sensible middle ground.
It’s generally best to follow your doctor or midwife’s recommendations. For some people, staying home from work for a few days or avoiding intense exercise can help both physically and emotionally.
Can my baby survive a threatened miscarriage?
Yes — in many cases, the pregnancy continues and the baby is born healthy. When a fetal heartbeat is detected and bleeding is light, the outlook is generally positive. The presence of a heartbeat reduces the risk of miscarriage significantly.
Other factors that suggest a better prognosis include:
- Bleeding that resolves within a few days
- No cramping or only mild cramping
- A closed cervix
- No clots or tissue passed
Ultimately, though, outcomes can’t be predicted with certainty — and it’s okay to hold space for both hope and fear at the same time.
Supporting mental health during a threatened miscarriage
No matter how things unfold, this experience can take a serious emotional toll. The stress of waiting, the anxiety of “what if,” the guilt (even though it’s not your fault), and the fear of loss — it’s a lot. Really, a lot.
Some ways to care for your mental health:
- Talk to someone. A therapist, counselor, or support group can help you process your emotions and feel less alone.
- Limit triggering content. Social media can be tough when you’re navigating uncertainty in pregnancy. Give yourself permission to mute, unfollow, or take a break.
- Practice grounding techniques. Whether it’s breathing exercises, journaling, or a walk outdoors, finding ways to come back to the present can help.
- Ask for practical support. It’s okay to need help with cooking, childcare, or just a shoulder to lean on.
It’s also okay if you feel numb, angry, or disconnected — everyone responds differently. Be gentle with yourself. This is hard.
Hope, fear, and everything in between
A threatened miscarriage is scary, confusing, and deeply emotional — but it isn’t always the end of the story. Many pregnancies with early bleeding go on to be completely healthy. And even if outcomes are uncertain, you deserve care, clarity, and support every step of the way.
If you’re dealing with a threatened miscarriage right now, know this: You didn’t cause it. You’re not alone. And whatever happens next, your experience is valid and worthy of compassion.
