My LMP was September 18th. On September 23rd, I took fertilization pills. I had sex from September 30th to October 1st with Guy #1. He came inside. Then on October 5th, I had sex with Guy #2, but he withdrew. After I missed my October period, I knew that I was pregnant. When did I get pregnant?

Answer

Based on your last period, your fertility window may have been between September 28th and October 8th. Being that you were with both men during that time, I cannot make an accurate guess. Keep in mind that pulling out does not prevent pregnancies.
