I just got off birth control orthro-trycyclin on Sep 8th and had my period on the 12th i have a 28 day cycle. However me and my bf had unprotected sex on the 22nd which he did not pull out. I started spotting lightly for 2days and then stopped (i was to ovulate on the 26th). I am now 6days late on my period, I have taken a pregnancy test after missing for 5days and it came up negative, however it had only been 3wks since we had sex, could i have taken it too soon? I have been nauseated for a week now as well as having mild cramping pains like i have a brick layin on me. I am also having shortness of breath when im not doing anything......Can anyone help me??????
