My doctor said until 20 weeks .

I looked into this & around 16-18 weeks I think the risk of it gets worse. The baby's hearing could be damaged. I could be wrong, though. I know an inside range is a no-no. But I stopped shooting once I hit 15 weeks just to be safe. I would ask your doctor just to be sure.

Ok so many variables to that question. have you always done it..height ..weight...weapon size...recoil...I don't think it should be a problem as long as you use safety precautions as you would discharging any weapon.

Depends on the kick back if it's a hunting rifle or shot gun wouldn't because of the kick back
