Defeated, frustrated, and tired.

Suez

This should be my 17th or 18th month of ttc and nothing. I'm starting to lost count of the number of months. I feel so defeated and discouraged. I got myself checked twice by 2 different doctors at 2 different clinics and both telling me that I'm good and everything is fine. Then why am I infertile? Since I'm infertile, maybe just stop my period forever and save me the trouble of having AF every month for nothing.
