i'm a part-time newborn photographer for a local group of hospitals, and the past couple times i've worked i've been experiencing stretchy/pulling/crampy pains in my stomach across my belly button and down around my abdomen. the job is pretty physical, i push around a very heavy cart, and constantly bend, lift, rotate, and squat. i only have these cramps/pains when i'm working, and today has been worse than wednesday.

i'm not sure if this is just a normal side affect of working while pregnant or if i'm doing some sort of damage. i feel like such a loser since i know women in other countries regularly do much more strenuous work while pregnant, but i'm just nervous that i'm doing something wrong! i'm 17w4d, by the way.
