I have just recently started the birth control levora. I'm on my first pack and just took my fourth inactive pill. I have not gotten my period yet. I had protected sex a week after I started ( the Sunday method). Then two weeks later I had unprotected sex but my partner did not cum inside me. However I've heard it is possible to be pregnant off of pre cum? Am I pregnant or is my body balance off? I take my pills at 11 am but occasionally take them from 10:50-11.
