I didnt feel my second until 22-24 weeks. My first I felt early on. Not everyone is the same.
I think the more you think about it,the more worried you get. So just relax and maybe just lay down one night and talk to bubba or sing? And maybe something might happen? I thought my little girls movements felt more like muscle spazums lol, but when she was bigger it
felt like she was trying to excape haha.
Is this you first if so they give you up until 24 weeks to start feeling them. Or your placenta may be at the front so you don't feel them yet. It if your very active moving all day you won't feel them. Good luck in your scan tomorrow
