So around the 10th of september was the last time me and my boyfriend had sex, but I am on Tri- Sprintec ( a birth control pill) and we used a condom, and on the third day afterwards i made him get me the morning after pill, but i could have taken it to late. I had my period about a week ago, or i hope it was my period and not just spotting, but i was really really light it seemed like. But they have alway been light. So could that just be the birth control taking affect? And now im really nausiated.? Could I just be freaking myself out or could be pregnate??? :(
