I had IVF done recently. 2 weeks after the embryo transfer (29 Dec 2013), my beta hcg was 246. Doctors said 3 embryos were transferred. Then 4 weeks after the embryo transfer: a gestational sac (6x6mm) was found, no heartbeat, non-viable. 6 weeks after the embryo transfer: a gestational sac (26x14mm) was found, non-viable, and no fetal pole was detected. 7 weeks after the embryo transfer, some signs of miscarriage were found, the gestational sac was told to be similiar to 6 weeks 2 days while mine is 9 weeks. TheI was advised to take misoprostol.
Please help me name some common problems that may have led to my miscarriage. If I had IVF done again, what should I do? I have allergic rhinitis. I sneeze a lot and have a runny nose every morning. Does this affect my pregnancy after IVF?
