I think its just that every
pregnancy is different. With my son, it was a breeze. I had heart burn, but that was the worst of it. I carried high with him and gained 43 lbs. With this pregnancy, im having a girl. Heartburn is horrible, carrying really low, i am 27 weeks and have already gained 27 lbs. My cervix is shortening, placenta was low lying, but moved up. I have had swollen legs, feet, and face. A lot of pressure and feel tired a lot.
