I stopped BCP early March, got my period on March 12, 2008, April 18, 2008 and now it is May 27 and haven't gotten it. We did have unprotected sex but not necessarily during the "window". I have taken 3 HPT early last week. All negative. I don't have any symptoms nor any symptoms my period is coming. Could I be pregnant? I did have a low progestrone level with my 4 1/2 year old son's pregnancy and had to take a supplement for 5 weeks while pregnant.
