3rd iui failing bust 💔

I just don't get why. And it was disheartening how my doctor never even explained anything. There's no feedback as to why it wasn't working or or what other changes I could make. With only one specimen left I'm gonna put this on hold for 4-5 months until I can figure something else out. I don't know if there's another supplement I need to take or what's the plan. Feeling... defeated. And feeling blown off and used by the Dr.
