Unexplained infertility sucks and I don’t understand It

I would love some advice 😢 ttc 3 Years. Went to a fertility specialist a year ago and they found nothing wrong.

-I ovulate around day 13/14.

-ovarian reserve is excellent

-HSG was great

-Sperm is great

-hormones are great

-found out I have sub-clinical hypothyroidism and that’s being controlled with meds

- I’m 28 and my husband is 30

-1 round of clomid, trigger and timed intercourse. 2 follicles

-2 rounds of femera, trigger and IUI. 2-3 follicles

We haven’t really been trying, Just in the waiting period right now to be financially ready to do IVF.
