Carrying stuff: how heavy is too heavy

[photographerlady]

Okay I am moving house at about 19 weeks pregnant and when it comes to lifting and moving should I worry this early about heavy lifting and how much is too heavy? I'm practically six foot and pretty strong but so far opting out of moving any furniture.

Dont move the furniture - I know someone who did this and had a miscarriage (which started at the time). Guess she will never know if it was definitely linked but why take the risk? Advice is to only deal with weights you lift regularly.
