Realllly late? Now what?

Before the questions here’s the background. So I’m currently logged at 75 days late for my period. I got off of birth control(tri-sprintec) beginning of march(?) had one really long period and then April and May I had a 3 day really light period.(not normal for me I always had 5-6 day medium periods while I was on BC)And have not had anything since. I just got done planning a wedding and getting married. So now things are calming down I am trying to get it figured out. And I’m honestly not sure where to start.

I guess the question is, should I just see my primary care? Or do I have to find a different kind of doctor? I don’t really know what to do since I’ve never had anything like this happen before.
