Active job

Lauren • Hello! I have a 6 year old son from a previous marriage. My husband and I are are ttc our first together!
I just finished my first fertile window on my ttc journey. My job is very active with a lot of bending, lifting heavy objects, and fighting. I work in a jail around inmates and occasionally have to intervene in fights. I realize any blunt trauma to the stomach could cause a miscarriage, but could the bending and lifting also hurt my chances of conceiving?
