First doctor's appointment

After more than a year of being thrown around by my own emotions every two weeks I have decided to make a doctor's appointment. The reason I have been putting it off is because quite frankly I don't believe I am going to be helped properly. I know the bias doctor's have against 'women's problems' and I didn't feel like advocating for myself since I have only recently accepted the way I am living shouldn't be acceptable.

I am seeking advice on how to approach this topic with my doctor, as I am scared I am not going to be taken seriously. Any tip would be welcome!

Edit: welllll that went exactly the way I didn't want it to go. I thought I was well prepared, had my cycle trackers with me and wrote down all of my symptoms. I don't even remember what has been said but the conclusion is I'm going to try oxazepam for when everything gets really bad.

I asked about specialized clinics but he didn't know any so now I'm going to have to research them myself. He said I could go to the gynecologist but 'didn't know how they were going to help me' so I didn't get a referral. Then he also joked I could get pregnant so I wouldn't have to deal with the fluctuations as much :)))))

I just feel like I failed myself in not standing my ground and not taking my partner with me to back me up. I knew what to expect and I still felt like I just let the doctor dictate what to do whilst knowing the possibility of him not knowing anything about it. I know it isn't my fault but fuck man.
