also anembryonic gestation is a condition where the ovum develops without embryo in it.
has some evidence of causing blighted ovum.
Previous Blighted ovum is usually a risk factor for next one, but that doesnt mean it is 100%, it is a chance which cannot be given accurately.
What I am trying to say is, this is not going to be same for you always. You can have a normal pregnancy
You havnt said anything about the treatment of PCOS. You need to correct PCOS first to reduce the chances of blighted ovum.
Consult your Gync she may prescribe metformin
Femara's non label use is to cause ovulation. PCOS with drug assisted ovulation increase the chance of blighted ovum. But this may be the only solution if you want to get pregnant soon and there is always a CHANCE to have a normal pregnancy which cant be determined.
Yes your MD is true, the bHCG values are low to become normal pregnancy, if so you need to do D&C, and just have contraception
for some time as per your doctors advice and try for pregnancy.
I am sure you will have a normal pregnancy soon.
