    I was on birth control for more than 5 years. Dec 29 I got my period and stopped on Jan 1. On Jan 2nd, I started a new pack of birth control, BUT I ONLY TOOK 5 PILLS FROM THAT PACK AND STOPPED. Then on Jan 18, I fooled around (did NOT have intercourse at all, but he touched me and I think he might had PRECUM on his fingers, could I get pregnant?)anyway, On Jan 28 (two days after my "expecting" period) I started bleeding and it last 3 days, (WAS THIS JUST TWO DAYS LATE PERIOD? OR WAS IMPLANTATION BLEEDING?) Then on Feb 6,8,10 and 11, I had sex without protection with my boyfriend. Then I found out on Feb 28 that I was pregnant!!! (my period that was supposed to come on Feb 25, didn't come!!!) Went to the dr. for the first time on March 07, HE SAID the ultrasound showed nothing, just the sac, it was too early to see anything else, and that I was PROBABLY between 4 to 5 weeks(Gestational Age/from LMP), but my hcg blood levels showed that I was 5-6 weeks. When I went back on April 11, the ultrasound showed 10w4d with CRL 3.66cm ...SO FAR MY DUE DATE IS NOV 4TH. All the ultrasounds matched up to my 21 week. My last ultrasound at 21w4d the baby was measuring 22w5d. DR STILL DID NOT CHANGE THE DUE DATE!!! Why after 21 weeks the baby started to measure a week ahead?Which ultrasound is more accurate dating conception? When did I conceive, in Jan or Feb?Thank you sooo much

    I would say you definitely conceived in January. My sons original due date was nov 2 and he came on oct 29 and by my calculations plus keeping track of days my husband and I have sex he was conceived in January. When I found out I was pregnant it was the beginning of march and I was already 6 weeks...hope this helps.. Good luck to u and your little one!
