Today I lifted three car batteries seperately. They are around 40 lbs. I know I shouldn‘t have lifted them and now I‘m very worried. I‘m so scared that it will cause placental abruption. Woul I know if I had it whether it was mild or severe? I haven‘t noticed tenderness, bleeding, or any pain. But it still worries me. Is 40lbs that risky? Do you think it would cause miscarriage? Please help.
