Noone knows at 2 1/2 weeks tht their Prego. I found out wen I was a week late nd I was almost 6 weeks. I'd bet its wrong. Use an online calculator. I did nd hit it right on the head according to my doctor.
Thank you. I was just freaking out when they told me I was only 2 and a half weeks because there is no way. Im just gonna go with this calculater for now.
LMP isn't always accurate, your OB will probably do an ultrasound around 7-12 weeks to determine your true due date, I went to my first appointment thinking I was due July 7 according to LMP but ultrasound said I was due August 3 and baby is still in track for that due date, so it can jump quite a bit. Don't stress about it too much, due dates give or take up to a week anyway.
