Help please!!

I’ve been TTC for about a year now after my miscarriage. My husband before he met me had chlamydia 3 times, he got them all treated right away, I’ve done EVERYTHING to get pregnant, healthy eating, pre seed, ovulation tests, all of the old wives tales. Nothing is working, I just got some tests ran and put me on progesterone. Does anyone have any pointers at all? Could it be him?
