I had sex on October 16th, and at the time we didn't have a condom. it only lasted 5 minutes each time, once at night and once in the morning. He never ejaculated in me, well, he never ejaculated at all, and he peed in between each time. I took plan b within 24 hours and had a period 5 days after I had sex. I have been having cramping, nauseous feelings and lack of appetite the past few days. could I be pregnant?
