hello I just had a misscarriage about 9 weeks ago and found out that and now pregnant about 6 weeks, however i did not have a period after misscarriage. So I dont know my exact gestational time. I went for my second u/s an still no baby, but now I have yolk sac, compared to first u/s, i dont know my current bhcg level, OB wants me to have another u/s next week. I had blighted ovum misscarriage last time, do u think this normal or I will misscarriage again?
