A blighted ovum is an abnormal intrauterine pregnancy. It mostly occurs from an embryo’s chromosomes abnormalities. Therefore, every woman can face this problem during pregnancy.
Aging or irregular diseases leads a greater risk of blighted ovum as an embryo is more likely to become abnormal when you are getting older. It doesn’t mean a blighted ovum has never comeback. If you have ever had this problem, you will have a chance to face it again. But a recurrent blighted ovum doesn’t happen frequently.
However, a blighted ovum is considered a pregnancy failure that causes miscarriage. The risk of 1 abortion in general woman is about 10-15%. But the risk of 2nd abortion is not much, less than 10%. So that you don’t need to be very concerned.
In conclusion, a blighted ovum can happen again but the chance of several recurrent pregnancy failures is uncommon if you are not too old or not having a congenital disease.
