What are the chances of being pregnant after having unprotected sex 14 days after your period ? My last period was DEC,13 through DEC 17. Me and my boyfriend had unprotected sex sometime around the 30th and 31st. he came in me two times.we had unprotected sex everyday after that until the 4th of this month. I started bleeding on the 8th and today it stopped which is aweek before my period is due. I took a HPT but it was negative Opinions?
