I am almost seventeen and on New years me and what is now my ex-boyfriend had unprotected sex I noticed as it got closer to the date of my period I began to feel nauseous and spotted for two days then it stopped, although I got my period on time, still after my period I have felt like I was going to throw up most of the day and I still feel like I could throw up at anytime, is it possible that I could still be pregnant even though I got my period on time?
