Lifting first trimester

L

I’m 6 weeks and I work in the operating room. I have to lift anesthetized patients and instrument trays that weigh 30 lbs while wearing lead. Is this dangerous for my baby? Can this cause a miscarriage? I really don’t have a choice but to keep doing it. I had a chemical pregnancy in August and I’m worried about everything!

My lower back has been hurting.

Any nurses, CNAs or fellow surg techs out there who have any advice?
