I had sex a day after my period had ended with a condom, I'm 2 weeks and 6 days late to get my period. I've take 5 preg tests, all in the morning and have all been negative. Getting slight cramps. Could I be pregnant? And I started birth control 17 days ago..could it be that? My boyfriend and I got worried so we got the abortion pills and inserted and still haven't got my period. Help!
