Does anyone have the lowdown on how much lifting is ok in early pregnancy? I'm in v early pregnancy, a bit older and not that fit. Have this (probably irrational) fear that heavy lifting might put strain on abdomen and make me miscarry. I'll be in a situation where I may have to lift some tables and chairs. What do you reckon - is this ok? I've heard it's not good for mother's back etc but that's not I'm worried about, just miscarriage fear...
