I do patient lifting to a stretcher/ and sliding. i ovulated 6/10 6/12. can this affect implantation? when can i test? lmp 5/24 had chemical m/c.

No effect: Your occupation and your straining/exercise shouldn't affect your chances of implantation given that any pregnancy that occurs would be very small and be shielded from the pressure by the cushioning of the uterus. Only test if you don't get your period in two weeks. You should be in close contact with an OB/GYN if you're trying to conceive because of your age.
