Babies grow slow...... They aren't fully developed till they are 39 weeks and some people dont make it till then.... If the babies growth becomes a problem the doctors will pick up on it and take it from there...so right now its pretty early so just relax
A regular ultrasound that early makes it hard to get an accurate reading. Send message to OB and ask them.what they think.
I saw the baby and the little heartbeat but I'm worried he/she is not growing.
I had my first u/s last week and the lady said the baby is too small to measure from a regular scan, i was freaking out because the baby wasn't anywhere to be seen. I thought i was 7w5d. She did a vaginal one to determine how far a long i was, baby was only 10.3mm,7w2d.
