A positive IVF pregnancy test can feel almost unreal. After injections, scans, blood tests and the long wait for those two lines, seeing a positive result brings relief. Then, unexpectedly, a miscarriage happens.
It hurts.
And it often leaves couples asking the same question: “Why did this happen when we did everything right?”
The difficult truth is that miscarriage after IVF can happen, even when treatment has been carefully planned, and an embryo has successfully implanted. It does not automatically mean that the IVF treatment failed or that something was done incorrectly.
What Can Cause a Miscarriage After IVF?
Chromosomal abnormalities are one of the most common reasons for early miscarriage. Sometimes, an embryo develops with an abnormal number of chromosomes, and the pregnancy cannot continue normally. This can happen naturally and isn't necessarily related to the IVF procedure itself.
Age can also influence miscarriage risk, particularly because egg quality and chromosomal abnormalities tend to become more common with increasing maternal age.
Other possible factors include uterine abnormalities, fibroids or polyps, hormonal problems, thyroid disorders, poorly controlled diabetes, certain infections, blood-clotting or immune-related conditions and some genetic problems.
And sometimes?
No definite cause is found.
That can be incredibly frustrating, but an unexplained miscarriage doesn't mean another pregnancy isn't possible.
Risk Factors to Know About
Several factors may increase the likelihood of miscarriage after IVF. These can include maternal age, previous miscarriages, certain medical conditions, smoking, excessive alcohol consumption, obesity and some untreated reproductive or hormonal disorders.
The quality of the embryo matters too, although embryo appearance alone cannot guarantee a successful pregnancy.
This is why fertility treatment shouldn't end with embryo transfer; careful follow-up during early pregnancy can help doctors identify concerns and manage underlying issues where possible.
Warning Signs of Miscarriage
Bleeding during early pregnancy doesn't always mean miscarriage. Some women experience light bleeding and continue to have healthy pregnancies.
Still, bleeding should not simply be ignored.
Warning signs may include vaginal bleeding, passing tissue or clots, pelvic cramping, lower abdominal pain or a sudden reduction in pregnancy symptoms. Heavy bleeding, severe abdominal pain, dizziness, fainting or shoulder-tip pain require urgent medical attention because these symptoms can sometimes indicate a serious complication, including ectopic pregnancy.
Don't wait and see if symptoms become unbearable.
What Happens After a Miscarriage?
The first step is confirming what has happened. Your doctor may recommend an ultrasound and blood tests, particularly measurements of the pregnancy hormone hCG, depending on the circumstances.
Afterwards, the focus shifts from “Why me?” to “What should we check before trying again?”
One miscarriage doesn't necessarily mean you need an extensive investigation. However, recurrent pregnancy loss, certain medical conditions or particular clinical findings may prompt additional tests, such as uterine evaluation, hormonal testing or genetic assessment.
This is where individualised fertility care matters.
At Shivam IVF, couples can discuss their history, previous IVF cycle and pregnancy outcome with a fertility specialist and understand what may be worth investigating before another attempt. Dr Bhavana Mittal focuses on infertility and reproductive medicine, helping couples understand their treatment options rather than simply rushing them into another cycle.
If you're searching for a Best Fertility Specialist in Delhi, the right doctor isn't just someone who performs IVF. You want someone who listens when things don't go according to plan, investigates thoughtfully and explains what comes next.
A miscarriage can close one chapter.
It doesn't necessarily close the book.
