Does PCOS increase miscarriage risk after IVF?
I have PCOS and just got a positive beta after FET. I keep reading PCOS raises miscarriage risk. What should I actually do now?
Short answer: Some studies show higher early pregnancy loss rates with PCOS, often linked to obesity, insulin resistance or higher luteal hormone extremes—not an automatic sentence. Focus on prescribed support, glucose control if needed, and standard early pregnancy follow-up.
Answer #1
Risk is multifactorial
PCOS alone does not mean miscarriage is likely. Optimising weight before treatment, treating thyroid disease, and avoiding uncontrolled diabetes matter. High estradiol cycles with fresh transfers historically looked riskier than well-prepared FETs in high responders.

Answer #2
What to do with a positive beta
Continue exact luteal medicines until your clinic tapers them. Attend serial betas and the viability scan as scheduled. Avoid unprescribed blood thinners or high-dose aspirin myths from social media. Report bleeding promptly rather than waiting in fear.

Get matched to one ART-registered clinic after consent — not a directory of calls.
