I slept with my boyfriend for 6 years. We split for a few days and I slept with a friend once. Then got back together . I've been on birth control for years. took my last pill jan 28th. Lmp was January 29-February 1st. Doc said it would take me 3-5 months before I could get pregnant(clearly just wanted me out the room, didn't even go into detail about anything). February 2 we began trying. Feb 15th and 16th bf came in me for a fact. Feb 19 was when I slept with my friend. No protection, pull out method, was not enjoyed but doggo style. Slept with my bf 20 or 21st and came inside again. Somtimes beginning of march (1-15th) I had a negative Prego test. April 15th had 5 positive tests. April 19th had vaginal US. Too early. April 25 was due dated dec. 16th 6weeks3day. Heard heart beat. May 17th I was given dec 16th 9weeks 4days. All the reverse due date calculators say I didn't conceive until march 25(a whole month later) but concerns me that every women is different and how stupid some doctors can be.
