I m 23, 5 6 and 118 pounds. My last menstrual cycle started somewhere between july 2 and july 5. I had unprotected sex around 11 pm on july 15, but the guy swares he pulled out. then on 18th we had unprotected sex again and he admitted to coming inside of me. i took plan b an hour later and it was still within the 72 hours of what happened on july 15. however, it is now july 30, and i am having serious pregnancy symptoms like FREQUENT URINATION, FEVER, and some clear vaginal discharge. i had some abdominal cramping around the 25th. My breasts feel weird... they re not really swollen or visibly different... the nipples just feel weird. i m most worried about the frequent urination. even twice an hour. could this be from the plan b or am i pregnant? i ve taken three pregnancy tests but they re still coming back negative...... confused
