PCOS and closed tube

Adry • 29 with PCOS, married, TTC for 2yrs 6 clomid cycles and 8 letrozole, chemical pregnancy loss September 2019 trying again with IVF first FET ended In miscarriage in September 2020 and now waiting to start FET 2 🌈👼🏻

I have PCOS with one closed tube and another tube with some doubt of its ability to move eggs.

My Dr suggested

but I asked to try letrozole for 2-3 cycles before I move to

.

This is my first time trying letrozole I have already done 4 cycles of clomid.

Who’s had more success with letrozole? What else should I do to help?

When should I give up and just do
