Hellos I'm just wondering. I'm on baby number 2 and the only movement I feel is in my lower uterus but when I had my first which was a girl, her movements were more at the top of my uterus which is near my belly button now. But I'm only feeling moments near my panty line and Lower uterus? Anyone else? And what does it mean?
