Who to see?

So. My fiance and I want to have a baby. Badly. Which you already know, considering the forum we're on. :) I haven't gotten my period back since I stopped using birth control and it's been just over 6 weeks since my last cycle (problem #1), and my fiance and I want to see someone to talk about our fertility; make sure everything in our bodies is okay, how to physically prepare for conception, etc. So, who do I go to (problem #2)? my primary care physician? OB-GYN? I want to make the appointment and am overwhelmed with where to start.
