My LMP was 11/13, I don't know the exact amount of days in my cycle, but it always comes around the same day every month give or take a few. My due date is 8/20 according to ultrasound and 8/22 according to my doctors. When I use the conception calculators they say the 27th by LMP, I did have sex on 11/25 and 12/6. I was wondering if since my doctor's date is 8/22 it would have been too late from the act on 11/25 and the date is 12/6 and ovulation happened late? How accurate are ultrasounds and due dates using LMP?

The difference between 8/20 and 8/22 is not meaninful enough to worry about. Babies can be born within a week or more of a due date, before or after. My doctor doesn't even give due DATES, she gives due WEEKS. As in, "The week of 8/21." Any time that week. I think that's what you should accept as when the baby is coming because it will make you less crazy during the final month of your pregnancy.
Just by way of comparison, here are my due dates.
Baby #1, due August 12, born July 30.
Baby #2, due June 25, born July 1.
Baby #3, due January 27, born January 9.
Hardly any babies are actually born on their due dates!

This is some info I learned in College Human Sexuality. You ovulate approximately 14 days after your period starts. Sperm can live in your body for 48 hours. You probably got pregnant around 11/27. I would say you are due about August 21 (38 week pregnancy or 40 weeks from LMP) I would say you got pregnant on 11/25. Either way good luck! And if you are worried about if the daddy is the one on 11/25 or 12/6, you MUST get a paternaty test...it is only right for the child!

Your due date is 8/20.
The ultrasound is the most accurate measure of your due date. The due date on the ultrasound is based on your baby's development/measurements so that is the most accurate.
I understand that it can be confusing to have your due date change. Mine changed after I had my first ultrasound. I have another one scheduled for next month and it may change then too.
LMP is just a guideline. It does not take into account your ovuation cycle, when you conceived or when you implanted.
The ultrasound date is the most accurate.

Due date is just a "guesstimate" not everybody is exaclty 28 days.
Plus anytime between 37-42 weeks is considered full term pregnancy, so you can deliver "early" 3 wks or even "late" 2 weeks
My son was due August 1st, but i had him July 22nd..perfectly healthy..... Good luck
