So my Boyfriend and I had sex on May 2 I took a plan B that morning. Well we also had unprotected sex that monday May 4th and tuesday May 5th. I didnt take a plan after those two days. I came on my cycle May9th-12th. I have been feeling alittle weird lately like nausea in the morning , waking up in the middle of the night, and extremely tired in the evening . Could be a chance that im pregnant? My next cycle is June 9...
