ObGyn Appointment fpr Bloody Nipple Discharge - What to Expect?

I'm 32, AFAB, nonbinary. No lifestyle changes or medication changes in more than a year. Never been to an obgyn, but have an appointment with one for next week. I have been having bloody discharge from my left breast for a few months. It doesn't seem to be prompted by anything (like... I would say it's leaking? It just comes out without any stimulation or pressure) It's not like massive amounts. I noticed it initially because of stains on a bra when I was about to do laundry. Until recently, it didn't seem to me that it was all the time, but it's definitely happening a tiny bit every day now. I avoid the doctor because of stereotypical low quality care in the past where concerns were ignored or dismissed that did result in diagnosis of something being missed, to be discovered later when things got worse. Around two weeks ago, I noticed the discharge seems to be happening every day now, but also that my left breast doesn't feel right. I don't know how to describe it - it's not painful really (at least doesn't hurt like I would say a papercit or a headache does) but more like this very slight but constant uncomfortable sensation mostly in my areola and nipple area but maybe a little "deeper" (?). It's hard not to focus on it. I did try to do a self exam but couldn't really "feel" anything as I don't really know what I'd be looking for anyway. Feels normal to me. I just want to know what to expect from the doctor. Should I expect just a physical exam and some questions and then they'll pretty much know based on what I tell them? Will they tell me to wait a few more months and check back if it still doesn't go away? Is this the sort of thing they do a scan for or like an X-ray or something? Does that hurt if they do? That feels really silly to ask but I'm feeling very stressed out about the unknown. I'm not catastrophizing or anything - I understand there's probably loads of stuff it could be caused from and it most likely is not serious. I'm not looking for anecdotes about what it could be. Really just wanting to know what to expect from the appointment itself and any kind of normal follow up appointments that might be related to finding out what's going on with something like this. Tips for not crying during my appointment are appreciated, because my anxiety is going to make me bawl like a baby.
