Yes, I had never heard of a blighted ovum until that miscarriage. I've had two successful pregnancies previously. I didn't have a D&C. I misscarriaged naturally. My husband's advise to me was to relax (easier said than done), not think about it and have a few drinks and have fun...and that is exactly what I did and that is when I got pregnant. Now, I also took anit0xidants (acai 100 pure juice) and vitamins (prenatal, vitamin D, Calcium and Magnesium).
I also used the clearblue monitor for all my pregnancies. It pinpointed the exact time of ovulation.
I suggest you rest, relax, have some fun, maybe join a dance class or something you enjoy and get your mind off of it (I know it is just about impossible)...give it a try!
I've had my first blood test and the levels were 18000 which is normal for a pregnancy of 5 weeks but a blighted ovum could also give those levels in the first few weeks. I'm going to request another b/t and then u/s.
I wish you well and good luck!!!!
