Trying to conceive

I just turned 33 my husband is 27. Last March I took my iud out myself after doing tons of research. May I found out we were pregnant. We were so excited but after bleeding days later, multiple hospital visits I had a miscarriage in June. It's been a year since our miscarriage. Still no pregnancy. We've done a otc test for his sperm and it came back normal. So I started taking PregPrep 2 months ago. He has a daughter from a previous relationship and I have 2 from a previous relationship as well. But none together. We were heartbroken after our miscarriage. I see his face every time I start my period. Is there other things I can do? Please help!!!
