I had unprotected sex (intercourse without condom) with my boyfriend last Friday (13th May) but he only came on my face much later. We then went to wash everything off and then he fingered me but with the finger that never got the ejaculate. We then had a bit more fun before I gave him a blowjob and he came in my mouth. I took two postinor at 7.40pm on Monday (16th May) fearing that somehow I would still get sperm in me. I m of legal age but still pretty scared I might be pregnant. My period is supposed to be here these few days and I m experiencing a little tummy cramps but i m not sure if its normal or would my period be delayed.
