A friend of mine had a blighted ovum. She was told to wait a year to try to get pregnant again. She needs to have blood tests every so often to check her hormone levels, etc to make sure there is not the possibility of cancer. Talk with your doctor to see what he/she recommends for you.

I have a blighted ovum last march, they say that it is better to wait 23-4 months before trying again. Now im on my 5th week of pregnancy
