Is this amount of blood normal

I've had 3 other chemicals, and each time I bled and cramped a little more than a period, this time I'm bleeding like crazy, dropping clots that are larger than a quarter and tons of smaller ones, when I go to pee it looks like I'm bleeding out in the bowl (For context to how I know I'm having a chemical, we thought I was pregnant for a while, I woke up to test, peed on it and implantation pink blood came out for half a second, nothing more for a couple of hours and then started bleeding like crazy and it's just been more and more blood and clots since) My main question is, I know the ER/ob-gyn is most likely going to pull the "it's just your period" or "you're just anxious" card and I want to avoid that if I really don't need any help. I just don't know what's normal and when to be concerned.
