                        I had the same problem during my   pregnancy and my doctor found that   I don't produce Projesterone.    I had to go on Projesterone supositories for   14 weeks.  The bleeding stopped, but  my level of projesterone never raised.  Normal is supposed to be around 13, mine never  went above 7-8.  Feel free to e-mail me to talk  more.  Good luck.  Tania
