On 7/20 I had a brief sexual encounter in which the man was inside of me, but did not ejaculate until long after he pulled out. My last period ended on 7/15 and my cycle is typically 33 days in length. I know I shouldn't have been ovulating, but I was paranoid and took a plan b pill 12 hours after the encounter. 5 days later I experienced bleeding which lasted about 4 days and was lighter than my normal period.
Fast forward to now, 3 weeks following sex, and I have been experiencing waves of nausea and lightheadedNess for the last couple of days. Of course, I am totally freaking out that I am pregnant. Is it possible that the hormones from the plan b pill are causing these issues?
