If you were to lift a heavy box (say 40-50 pounds) in the first week after implantation, would it cause any damage? I'm 7dpo and lifted 2 heavy boxes at work today. One of them has left me with a small bruise just above my hip bone. They know I'm TTC and are keeping me away from the really heavy jobs, but I'm still worried incase I have to lift something heavy before I find out for sure if I am pregnant.
