Okay so my guy and I had unprotected sex onthe 13 of this month. He didn't ejaculate in me but I still took the Plan B pill about 15 hours later. I didn't get any of the side effects at all. Now my periods are usually on time. According to my app I was supposed to get it yesterday June 25 but I haven't gotten it. I only had just a bit spotting so far but no full period. Is there a chance that I could be pregnant?? Thanks guys!
