I wouldn't worry.... I didn't feel my baby kick till I was close to 23 weeks.... I was so scared because people kept telling me i should have felt him but every one is different.... It just depends on how sensitive your stomach is and how often they are actually moving... And remember at this point your baby is pretty small so it is easy to confuse movement with gas pains or indigestion
Is okay sometimes you don't feel it till your six month..
I had my ultrasound at 17+6...saw her moving around the next day I felt her kick :).... You will feel baby soon...being ftm we usually feel them later than others :)
im also gettin my ultrasound tommorow! i hardly have felt my baby im 18weeks. im sure all is good!
You could just not be noticing yet, some people feel anywhere from 16-22 weeks. You'll feel your baby boy/girl anytime now, and have fun in the morning! I love the ultrasounds and it was amazing finding out its a boy, he wasn't shy at all. Good luck!:)
