Reproductive endocrinologist

Whelp, hubby and I have been trying for six months now. I know they say you should wait to go to the doctor, but in my younger years I was diagnosed with endometriosis and PCOS. After we got married this year, we started trying to conceive. The first month off my pill, my cycle was a perfect 28 days. However, ever since then it's been pretty erratic. My doc explained to me that it may be related to PCOS as my cycles are very unpredictable. He recommended me to a reproductive endocrinologist. Luckily he's open tomorrow and I'll be seen him then.
