I’m due March 30th with a baby boy, i’m 18 weeks and 1 day as of today. A lot of women I see have felt kicks or flutters. I feel like I felt one flutter while I was doing my hair but it never happened again so it might’ve just been me.. is this normal that I don’t feel anything or should I talk to my OB?
