My ob is giving up on me 😭

🎀GirlMom 01/2023🎀
So I've had 3 mc so far. One in 2013 & the other 2 this year in March & July. I didn't get diagnosed with PCOS until early last year after TTC for 3 years. In March I got pregnant off metformin 1000mg alone, then in June my OB added clomid 50mg & that worked the first round. So today I got a call and the nurse said my OB wants to send me to a fertility specialist 😭 she haven't checked my progesterone to see if that was a issue or a genetic testing... So she said I can come back late august to see if there's anything else she can do.. Is there anything specific I should ask as to why I can't sustain a pregnancy? (Feel like pulling my hair) grrrrrrrrr! It seems nobody understands how hard I'm trying.
