We had sex last February 28, 1pm, the last day of my menstruation was on February 25. While at the moment, my boyfriend said that he felt some release from his penis. He said that it is not a sperm/semen. He pulled it out and ejaculated 5 minutes after. After the deed, we became paranoid and searched and found out that the release is called a pre-cM. My boyfriend said that he masturbated before our intercourse in the morning 5 am. Then, we searched and found Nordette. I took the first dosage (4x) as soon as possible on March 1, 4pm and the second (4x) at 4am. The pills made me nauseous and I experienced headache and I was feeling down for 3 days. And on March 7th, I had bleeding 3-4 days. It was heavy and unusual because I usually bleed for 5-6 days. I am regular ever since I had my menarche.
I still don't have my period until now. I am paranoid. We are anxious.
What are the chances of me getting pregnant?
