Period is so heavy… losing to much blood..

**update** went to the ER and they did blood testing and spent 45 min doing a ultrasound and they found a small cyst on my right ovary, but they said it wasnt enough to worry about it and basically said I just have a menorrhagia … and that i just have heavy periods I guess..

2 nights ago I woke up to INTENSE cramps.. feelings of like contractions.. it kept me up all night.. I had to miss work the next day.. went to work today and left cause I had been bleeding THROUGH my ultra size tampons.. Went back to work .. emailed my dr about how heavy my periods are and that this cycle feels very different.. told them I’ve been having blood clots size of a quarter.. and when I sit down on the toilet, my vag hurts so bad and feels dull/achy..they told me to go to the ER … at the time I didn’t feel I needed to go for something like this.. its now 12am and I just got up to use the bathroom and literally gushing out blood.. a PUDDLE of blood in my underwear.. went down my legs and all on the bathroom floor.. I keep having to change my tampon every 1-2 hours.. now it’s 10x worse.. my sides hurt sooooooo bad right now and I have no way to go to the ER with my kids.. I’ve taken Tylenol for pain.. nothing. I feel weak & super cold in my legs..

I’m 23 and my bf and I have been ttc since our pregnancy loss in august and no luck since then..

Has anyone had this happen before ?
