After my ultrasound i was told that i am further ahead than i think i am?

Question

Has this happened to anyone else that is positive they know when they conceived? It was only by about a week based on the size of the baby.

I believe i am 11 weeks.

Answer 1

Yup. They told me I was a week further than I thought I was, but I was rather sure of when I conceived. I'd only had sex once, so there was no way I could have conceived before then. A later ultrasound said that the baby was smaller than they and I thought. Right now I'm just on the path that I know when I conceived, as there could only be a few days difference even if I ovulated late, so I'm going by my own date.

Answer 2

thats nothing really. There is a 2 week margin of error for the conception date. My date changed 7 times with my first baby. Thats why you are considered full term at 36 weeks an you can go over by 2 weeks without any concern. Don't worry about it. There is a good chance it will happen again. Those dates change constantly. As long as its no more than 2 weeks there is no need to worry or thats what they told me anyway.

Answer 3

I knew that my due date was about a week off, since I know I ovulate later in the month than most women. When I had my ultrasound, they confirmed it. Then again, she came 3 wks early so none of the due dates even mattered! Either way, I would just be happy that the baby looks normal and healthy and be glad for that. Good luck and congrats!

Answer 4

Ultrasound measurements aren't always accurate. With my second son, I had one on a friday. They told me he was about 7.5 pounds. The next day, I delivered him by c-section (emergency) and he was 8 lb. 11 oz.

Answer 5

dont worry soon they will give you another ultra sound when the baby is 23 weeks i think

Answer 6

Nothing to worry about,you just miscalculated.
