My question is who is the father of my Baby Guy A or Guy B - I had my period september 5th 2011 then condom broke 22 and took plan B pill the 24th recieved a period Oct 1st. Had sex with guy B all through Oct. Conception was oct 15th My Last ultra sound put baby at 13weeks 5 days but from Oct 1st to Jan 11th Baby age by that is 14 weeks .I found out i was pregnant the first of november when i didn't recieve my period and confirmed it november 15th. My question is would the ultra sound show the baby being older even if they put in the date OCT 1st and is GUY B the father?
Welcome to ehealthforum,
Early ultrasound scans can detect gestational age with accuracy of +/- 5-7 days. The bleeding after taking emergency contraceptive could be the withdrawal bleeding (usually occurs within 5-7 days of taking the pill indicating that it was effective). If there was period between two different sexual encounters, then the intercourse after periods would result in pregnancy. Taking your LMP as Oct 1st (the withdrawal bleeding date as described by you), your next ovulation would be around Oct 15th, and conception could have occurred between Oct 11-19, 2011, and your due date would be around July 7th (completion of 40 weeks of gestation). The ovulation usually occurs 8-14 days after your first day of menstrual bleeding (the exact date of ovulation can vary from woman to woman) and the intercourse closer to ovulation time results in pregnancy, and so the actual conception date would correspond to date closer to ovulation date. Ultrasound scans done for dating can also help with knowing your probable conception date. The exact results can only be made out after a Paternity test. Visit your doctor/gynecologist for further assistance and clarification.
