I have my first appt yesterday. I am 8w4d with baby#3. Doc said I’m measuring big at 9w but due date will stay that same since it’s only a week. My due date is 12/10.

So does that mean I am 9w or is baby just big. I know dr said doing the scan will give a better age vs LMP

Also, this may be a dumb question. But is the sac supposed to be that size. I see other people’s US and it looks like the sac is so much bigger! Was it how the pic was taken??

It was a transvaginal US

Thanks in advance
