Q: I have gone through ivf two times, both times, i was found pregnancy, ,both time beta hcg rising in double value. in the first pregnancy, only sac found, no fetal pole and nothing else and ended with the pregnancy. Second time, i found pregnant again and then at 5th week, I started bleeding. This time no sac, no fetal pole, what is the reason in ivf for the same. I am really worried. If pregqnncy is there, why misscarriage happen everytime.
