I'm 23 weeks and just now started feeling her move. She loves kicking my bladder and it hurts so bad Lol. I was so worried when I couldn't feel her that my Dr had me come in for a heartbeat check and a couple days after that is when I started feeling her. Try not to stress too much. It will happen.
Depends sometimes mothers don't feel their babies for many reason but sometimes we can dismiss the movement as something else like tummy rumbling or cramp when he or she is bigger you soon will get the rib kicks and tummy punches. Good luck
I didn't feel my first boy move until he was 23 weeks. It's new to you and the uterus is a strong muscle. The second pregnancy the uterus is wore out more so it's easier to feel movements earlier. This pregnancy I felt my next boy move at 17 weeks.
