29 weeks at the moment, is it normal for me to feel so front heavy that it's making it hard for me to be up and walking? at this point Idk how big baby is, my ultrasound tech never told us at our ultrasound we last had. but I feel really bad that I have to sit everytime I get done walking from a few moments while helping clean the house because my boyfriend's mom is harping on us, especially me.
