I didnt feel anything till 19wks... I have an anterior placenta and it must have blocked a lot of those early ones... I also never recall any "squirms" it "gas bubble" feelings people often talk about ar 14-16wk.
Straight to bigger movements at 19-20 but still not consistent until 25-26wk :)
Although I felt mine early on. My friend didn't feel her baby kick until 22 weeks. On the 20 wk ultrasound they could see the baby squirming around, but since her placenta is in the front (anterior) it block the feeling. I think you're fine if everything else is going well!
