My last LMP was January 23rd, and I had sex with my guy on January 28th. When did I get pregnant?


Based on your last period, you may be around 5 weeks 6 days pregnant. Your fertility window may have been between 2/2-2/12. Any intercourse you had around then may have caused the pregnancy. If you were with your guy on January 28th, it's possible that either his sperm lived in you until you ovulated, or you ovulated early.
