When could you feel your baby?,

Start off with I'm a bigger girl 240 before I got pregnant I'm 232 right now. I was wondering when all you mommies felt your baby really move? I can feel little flutters here an there I'm 20 weeks this Friday the 14th I just wanna know when you really noticed it? my doctor says she is still kinda far back when we went to listen to hear heart rate she still had to push kinda hard to hear her. So i take that will effect when i feel her.Also when could you feel them move on the outside? Boyfriends dying to feel her move an I just keep telling him he will soon...
