Measuring wrong??

hcarp0408 · Mar 30th, 2012, 16:32 PM

My first ultrasound I was 10 and a half weeks. But she (I am now 26 weeks and still trying to figure this out) measured at 8 weeks and 4 days... My husband is in the military and I know FOR A FACT that I could not have possibly gotten pregnant past the 18th of Oct and my lmp was Oct 1st. My periods are always like clockwork every 4 weeks. They are trying to say my due date is july 20 which meant I conceived between the 24 of oct or 1st of nov and there is absolutely no way that could have happened. For one, my husband was gone, two we hadn't had sex in 8 days, and three I was missing my period by the 29th... Has anyone had this problem??
the dr keeps saying I'm wrong and its stressing me out trying to plan for her and its throwing my tests off so none of them come back right and they wont do anything. Help??

Once you have sex, the sperm can take several days to travel up to meet the egg, then the egg can take a few days travelling to the uterus and implanting. So possibly you had sex on the 18th of October and the egg didn't implant till the 24th.

I would go with the scanned dates because they are a lot more accurate. They only used LMP because you used to have no way of knowing what date you actually ovulated and how long implantation took. The scan date takes those into account because it is a measure of how long your little one has actually been growing in there.
