I am so glad to find this discussion hopefully it can help ease my mind a little. I am currently 33 weeks and 5 days pregnant. According to my lmp I am due May 1st. According to my earliest ultrasound done around 9 weeks I am due April 30th! I am 100 percent sure my last period was July 25. My cycles range from 26-28 days. Lately it's been right at 28 days. My dates of intercourse were July 22 and August 7 both unprotected with guy A. (Pull out method) .. i slept with another guy on August 10th around 1am protected (condom) . We also had sex August 13 around 1 am unprotected. I'm not sure if he pulled out that day but he says he did. I was expecting my period aug 21 st but it never showed. Took a test on the 24th and it was indeed positive very dark lines. This whole pregnancy I've been measuring a Lil ahead . I have growth ultrasounds every 6 weeks and the baby is measuring a week ahead and all they say is I'm right on target. My fundal height is also measuring ahead like a week. I got an idea but not very sure on which sexual intercourse led to the pregnancy . Can someone help me figure out? Both men are aware and a DNA is in the future. However i wanna ease my mind a little because it's been rough.
