I am 33 years old and I have no children.  After years of trying to conceive with my ex-husband of 8 years, I went through tons of fertility tests to find out nothing seemed to be wrong with me.  I had two miscarriages and then a pregnancy that the doctor's terminated at the beginning of the 2nd trimester because the heartbeat was decreasing rapidly and they said they was no chance of the baby surviving outside of the womb for more than a few hours if I would carry to full term.  Years went by and I found out it was my ex that was the problem.  Low sperm count.  Since then, I met a wonderful man who already has a child, so we are pretty darn sure he is ok, but since we have started trying to conceive, I have went through two more miscarriages in less than 6 months!  Both ended around the 7 1/2 to 8 week mark.  Right around the time I find out I'm pregnant, everything seems fine and then both times we decided to have sex and I bled lightly a few hours after, which we thought was just from the sex, but then I miscarried both times the day after we had sex.  Could the sex we had have caused the miscarriages?  The doctors cannot find anything wrong with my blood tests, my hormones or the condition of my cervix besides a little bit of scarring from the pregnancy that was aborted by the doctor's, but they do not believe that do be enough to cause a miscarriage.  A couple of my friends had similar issues and they were diagnosed with a blood clotting disorder, so after I miscarried the 2nd time, I started taking baby aspirin on a daily basis as a blood thinner, but that obviously didn't help!  Even after I started bleeding, the doctor examined me and my cervix was closed.  Has anyone else experienced problems like me and went on to have a successful pregnancy?  I want to get pregnant again and I obviously don't have that much difficulty getting pregnant...it's staying pregnant that's the problem! If anyone has any information that may help me, please feel free to share!  My biological clock is ticking and I really want to get pregnant and stay pregnant!
