Please help :( period for over a month?

Hi ladies!! I’m super concerned about my health atm. Ok so a little back story in I’m 24 years old & and I have a five year old. I don’t think I’ve ever had a Pap smear or any test regarding that even though everyone tells me they do one when your pregnant but I don’t really remember 🤷🏽‍♀️ or maybe I just don’t know what they are lol. Anyways, In the first half of 2018 my periods were really regular(even before 2018 I’ve never had any problems), 2/3 days most of them were pretty medium/light flow until maybe the second half of 2018 I remember missing my period 2 months I even thought I was pregnant. But finally got my period, the weird part of this was it lasted 2 weeks.. then I remembered my period was 2 months late and since that happened after my birth control that I had for three months when I took it off my period lasted 3 weeks. In my mind I’m thinking well since it was skipped a month well add a week to my period didn’t really think much of it🤷🏽‍♀️ don’t know if it’s normal or not anyway it happened again. After my 2 week period it skipped 3 months which we go into January of 2019 where I got my period for 3 weeks.. so I’m thinking maybe this is my new normal? Which lasted all the way to February. I didn’t get my period again until the last week of March for about a week but now I’m noticing heavier periods, April I get my period again for about a week and also heavy then come May I get my period for two weeks and super heavy. I usually use tampons and never went above the “regular” flow marked ones but in May I soaked up the “ultra” (for heaviest flows) in minutes!!!! I even had to leave work bc of that. After May I stopped using tampons and switched to pads but the overnight super thick ones bc of the flow in June was the same. After that I lost my phone so I stopped tracking my periods but I’m pretty sure I’ve have more than a month on my period now :( and it varies by day some or super heavy, some are only spotting some are regular but on my heavy days (even in March, April, May, June) I’ve been having like big (TIM😖) blob clot-like stuff coming out and they are HUGE. And I read online that they shoudnt be bigger than a quarter and mine are super huge it’s scaring me and I know I need to go to the doctor but my period hasn’t even stopped and idk to what kind of doctor should I get, not to mention I have no insurance :/ I will eventually make an appointment but I don’t I guess I wanted to vent about this, I’m super worried. Can anyone help as to what kind of doctor I should see? What questions should I ask? Can I go see a doctor on my period? Idk please help

***update I’m currently not on birth control and haven’t been on bc for about a year and a half***
