Hello Sir /Ma am On the 5th of March (3 days back) me and my boyfriend had not exactly have sex, his penis was basically rubbing against my vagina for about 20-30 seconds. There was no condom on either of us. Today morning, I had an Ipill (about 68 hours from the time). Also, at around 11ish today, I did the urine pregnancy test, which came out negative. From what I ve read, I gather that it s too early for the urine test to answer positive, even if I am pregnant . My periods are due on the 23rd of this month. How can and when can I be sure that I m not pregnant? Please help me out. Thank you
