Im just wonder I am 18 almost 19 weeks pregnant and I feel like I don't feel the baby move much and don't feel very pregnant except back pain and hunger, but only feeling in my stomach is pinching feelings and some times one day I don't feel anything and another day I'll feel the pinches again .. normal? I lost my first and just don't wnt that to happen again
