Hello Thanks for writing to us with your health concern. A previous voluntary termination does not affect future pregnancies generally. A missed miscarriage and a blighted ovum are due to chromosomal anomalies. They are not generally due to the aftermaths of a previous abortion. Risks of repeated miscarriages include - pelvic infection, uterine scarring and adhesions, tubal blockage, cervical canal incompetence. Yes, you may face difficulties in next conception. Wait for atleast 3 - 6 months before planning your next pregnancy. Take regular folic acid supplements meanwhile. If you fail to conceive / menstruate regularly consult a gynecologist for detailed evaluation. Take care.
