I'm on the far NW side but my Ob/Gyn is Dr.Joseph Montgomery at Cy-Fair Hospital if you happen to be on thise side of town.
He isn't the most up to date person on PCOS but he does know what it is and he IS learning more about it since having a few strong PCOS'ers come through his office lately
If you like your RE though and trust his/her opinion, they should be able to give you some recommendations over the phone, no matter when your next appointment is.
GOOD LUCK

!!!
