Help :( Been bleeding for 18 days now.

So I’m in the situation where any gynecologist is open from 8-3 or 5pm. My work schedule is 7-6pm and it’s not a job that I can just leave because they need me here.

It’s been 18days since I first started bleeding. I’ve never bled for this long nor has it ever been this heavy. There’s a lot of blood clots and it will be light brown when I think it’s going away but then it’s bright red. For example this morning when I woke up I thought finally it’s going away then after a rush morning at work (I was stressed) I was bleeding bright red also pinkish. No cramps. Rare lower back pain and can’t remember if I had any abdominal pain.

I’ve gone through over two boxes of tampons.

I don’t know if it has anything to do with me stopping my birth control. I stopped taking it end of January to attempt to conceive. Last few periods have been fine. It’s just this one that has me wondering what the hell is going on.

Does anyone know what could be the issue?

Please help :(
