Report this. On the notes for the dr she put dates don't match not sure of viability of pregnancy It would also help to know how far off you think it is. In the first trimester, ultrasounds are usually accurate for dating, give or take a week.
So, if you'd shift your due date within a week one way or the other, they yes that's normal.
With my first pregnancy, I had an ultrasound at about 12 weeks. They gave me a due date of September 29th, which corresponds to a conception date of January 6th. That wasn't possible. Conception was December 27th, 31st, or January 1st.
Given that I had nipple tenderness that was very noticable and uncomfortable on January 8th despite not nursing or doing anything to provoke itthe date of the 31st or 1st is unlikely because baby would have just implanted or not at all.
So ultrasound was off by at least days, more likely If you're saying that you had an ultrasound in the first trimester and you think it was off by more than 2 weeks, then that is extremely unlikely.
You dont have doubts that your date is wrong, you have doubts that it is right Im going throught the same thing my dr told me my first due date would be august 31 but around 12 weeks he changed it to September 8thso im still going with my old due date since with my first pregancy the same dr told me that my daughter was only going to be 4lbs so they let me go almost 2 weeks over due, and she ended up weighing 8lbs 1oz and was to big for me to handle, so i dont always believe what your dr tells you sometimes they are wrong!!
Answer Save. So if its the 20 week scan they're probably right.
