Thinking of going to a fertility doc

I'm 31 and my husband is 32 and we've been ttc for 10 months and haven't had any luck. He got his sperm checked and everything was fine but now I'm getting worried that something might be wrong with me. I got a blood test to get my progesterone checked and everything was fine too. Should I go see a fertility doctor or just keep trying? What kinds of things do fertility doctors test for?
