I did not feel my baby girl move until 19 weeks it's diffrent for everyone
I am 21w2d and dont feel my guy yet bc.my placenta is in the front. Don't be alarmed. :)
I didn't really start feeling mine until about 19-20wks & since I'm a FTM, I'm assuming it's why I wasn't sure if it was really her. I've read that movements are sporatic at this time (I'm now 22wks). I can't, however, feel her on the outside. The sonogram will give you peace of mind though. I wouldn't worry until you're giving something to sorry about. :)
It can take anything up to 24 weeks to feel first movements especially on a first pregnancy so dont worry
Ull be grand u night feel baby move for a while x but if ur worried go to doc.
