I just went through the same situation. I had 3 embryos transferred on 6/21. I got a positive pregnancy test on 7/3. I started bleeding with cramping on 7/17. Went to the doctor and miscarried two. I still had one baby with a heartbeat there. On July 22, I lost the last one. The doctor told me some bleeding was normal. I just want to know what went wrong. I was 6 weeks pregnant and getting very excited about being a mom. I hope everything goes well for you. I hope you have a much better result then I did.
