Appointment scheduled with Fertility Specialist.

I’m going to see a specialist on the 25th of June. Husband and I have been trying to conceive #1 for 3 years with no luck. Husband had a semen analysis and everything looked great there. I have regular cycles and consistently get positive OPKs in the middle of my cycle. Has anyone experienced the same thing? What did you find out when you saw a specialist? Some months I feel like I’m falling into a depression because I can’t seem to do what my body is supposed to be able to do. I’m 31 years old and I waited until now (3 years ago) to try for a family because I wanted to have my life together before having kids. I didn’t know it was going to be so hard...
