Q&A: Do I have a blighted ovum or is this a chromosomal anomaly?
I'm turning 42 this January and I tested positive in a lab blood test for pregnancy. On the eighth gestational week, I experienced bleeding, clotting and cramping. The doctor looked at the ultrasound and said there was no pregnancy, despite the HCG levels. He suggested the possibility of a blighted ovum.
My own research has pointed to likely chromosomal anomaly in the case of an embryo that doesn't implant correctly and is then reabsorbed. Is this something that is considered an accident in most cases, or will my husband and I require testing if it occurs again? In addition, the doctor said we should wait three months before trying again. Why?
A blighted ovum can be a pregnancy in which the actual fetus didn’t develop or was absorbed before it was big enough to be seen on ultrasound. In either event it’s a miscarriage and requires no special testing unless it were to recur.
Waiting three months is just a way of getting the full hormonal effects of the previous pregnancy out of the mix before conceiving again. It’s not crucial, but since you’re afraid of another miscarriage, you would want to know that you did everything you could to stack the decks in your favor.
