The first day of my last period was on January 22nd. I didn’t start having intercourse until the week of Feb 5th. I took four pregnancy tests March 10th-11th. They all came back positive. When did I get pregnant? I don’t recall getting my period in February, either.
Based on your last period, your fertility window may have been between February 1st and February 11th. You most likely became pregnant around that time.
