When do you think I should see a doctor?

I don’t have a normal doctor so I’m not even sure who to go to for this but I’ve been bleeding on and off since beginning of October. It stops for maybe a day or just through the night and then it’s just light bleeding. Sometimes it’s dark red sometimes it brown and idk if I should just let me body do whatever it’s doing or see a doctor? It doesn’t hurt and I don’t feel any cramps or anything like I would with my period. Usually my period only lasts about 3 days so I’m not sure what’s going on. But i only stop bleeding for a few hours and then i will randomnly start bleeding again. So should I see a doctor? Has this happened to anyone else? Should I just let it run its course and wait??
