TTC 2 years after Depo,clomid, etc

I was on depo shot for about 7 years. My husband and I decided we wanted more children. Stopped depo 2 years and 2 months ago. Tried naturally for a year with no luck. OB referred to a fertility specialist multiple test, blood work and semen analysis and everything is coming back normal. Tried clomid for 3 months and no luck. Just had an iui completed last week. At this point I am deflated and dont know why we aren’t getting pregnant. Anyone have any advice? This is straining our relationship. 😔
