On october 4th was the last day of my period. The next day, on october 5, me and my boyfriend had unprotected sex, he came in me twice. The rest of the day I had cramps.The next day about 24 hours later I took plan b. It is october 9, and i have still had cramps and am now experiencing back pain, egg white discharge and bloating. I never have any symptoms after my period, and let alone when i'm on it. So i was wondering could i be pregnant? My period isn't expected until oct. 27, but my periods are pretty irregular.
