I'm 18 weeks pregnant now. The app shows by this week I should be able to feel baby's movements and kicks. But I don't feel any yet. I know each pregnancy differs. But when I search articles it is showing some experience baby's movements as early as week 16. But I am already at 18 wks 4 days. This is making me little worried. Should I consult my gynec sooner? #firstbaby please help
