Thanks for the information. For me it's been ten years and i'm starting all over. I had a tubal then 2years later I had a reversal and the doctor told me after having some test done that the reversal did not work.But I thank God everyday for his blessing I'm know 17 weeks pregnant and very excited to be a mom again .
After 13 weeks babies grow at different rates. At my 16 week my baby was measuring at 17 weeks but at my 21 week she was right at 21 weeks. I wouldn't worry about it unless the baby is severely under or over weight. My son always measured big and the drs told me he was going to be a big baby at around 10lbs so they induced me at 39 weeks and he was 7lbs6oz so they can deffinently be off on the measurements as well :)
Babies range in size, just cause the baby is large doesnt mean you are further along. If you are worried call you dr and ask about it.
