Trying to conceive.

I had a missed miscarriage about a year and a half ago (had to have d&c;) and have found out that I have a split uterus. Since then I have been ttc but have had no luck. I was on nexplanon for about 10 months after my miscarriage. Im not sure what else I can try to do? My husband is also schizophrenic and sometimes can't get it up because of meds(sorry tmi) but im not sure if it's him or me and what steps we should take..
