Is it normal to have this type of period complications?

Female, 18 - never been sexually active.

For quite some time now I've been having blood clots each time I get my period. Literally the day I start my period, I find out 'cause I'll see clots when I look down. The sizes vary, but I'd say a good amount of the time they are bigger than a quarter. My cycle is pretty irregular, there has been 2 times where I have had my period twice in the same month. I get cramps, sometimes not bad - other times I feel like my uterus is about to fall out of my vag, literally can't move or do anything at that point because it is so sore & feels like my muscles in there are tightened, stretching, being put to work, etc. My exaggerated description is to compare how it would feel to have a train ran on you by multiple people lol. I got my period when I was 10 years old. I've always used pads, but I've started going back & forth between pads & tampons. I've never been so great at keeping track of my period but things have gotten to the point where I've downloaded an app on my IPhone to mark them down & list my symptoms & treatments & little notes I can add whenever needed.

I have a lot of health conditions, disorders, & etc. For a few years now, for each month I would become anemic & feel really tired, drowsy, & bruise easily. It's been like that for a looooong time, up until somewhere between mid-summer & august things took a DRASTIC turn & got extremely bad. I was hospitalized for a week. I was dehydrated, I wasn't eating, literally a health bar would fill me up for the day, I got extremely light headed, dizzy, spaced out, my skin was losing it's color, my lips were turning gray, I was shaking, I could barely even walk, when I went to the hospital they said I lost 12 lbs, all this had happened in the course of a weekend, it only took until Monday had come for when it got even worse. They had tried to hook me up to the IV to keep me hydrated & had stuck me so many times because they couldn't get any good veins out of me, they said I was "running dry". It was terrifying. My anxiety was through the roof because nobody could figure out what in the hell was happening. I saw Dr. after Dr. & none of them could explain it. The hospital wanted to make sure I get seen by every Dr. for every part of my body to verify everything was working normally. The 2 oddest things of all were 1. I had gotten my period, normal just like every other, blood clots & all, & normally when I get my period I get the munchies & during that point I didn't wanna eat; 2. Each Dr.'s examinations said I was completely normal & had a normal blood count whereas when I first got admitted I had a blood count of 10 I believe? or 11? One or the other. That was half a year ago & I still have no answer as to what happened.

I went to the hemotologist/oncologist, got checked for cancer which came back negative. & since have been put on iron tablets as a treatment. So far so good but still had blood clots each period. The duration is normally 7 days.

Oh, I should also add that this isn't the first time having difficulties when it comes to blood. When I was a baby I had a low white count & they suspected I had lukeimia & I had to undergo a bone marrow aspiration. Dr.'s had told my mom that they believed I would out grow it but here we are today lol...

& BTW, I also have a cyst on my liver that complicates the option of going on birth control, ever because the cyst would then take over my liver & I would die. I've yet to see a gyno to figure out what the hell is up & see what my other possible options could be.

Anybody have any clues, insights, similarities, etc.??
Anything would be greatly appreciated.
