Re: Miscarriage
When I had my miscarriages, there were warning signs that things were not going well. First was that my blood levels of pregnancy hormone were increasing too slowly. It should double every 24 rto 48 hours - mine was doubling every 4 to 6 days. I also got cramps intermittently, low back cramps. Both times, the heartbeat stopped between week 6 and week 8. I had pathology done and it turned out that both times, it was a bad egg, that although the egg was fertilized, it could never have developed into a baby.
For my successful pregnancies, I never had a moment of nausea. I got extremely tired and extremely hungry but those were the only typical symptoms I ever had.
