It sucks that he has to be gone all day I really need help with the kids now that I’m pregnant it’s like I can’t move around like I use to anytime I have to clean as far as sweeping and mopping or even picking the kids up to get them in or out of the tub or their bed or even going up and down the stairs my stomach and back will start hurting almost immediately even if I raise my voice to yell it’ll start to hurt I’ve never went through this with my other pregnancies and Ik every pregnancy is different I just don’t understand why this one is so painful
