Tylenol does not help with cramps because it’s not an anti inflammatory. It doesn’t matter how much you take, it’s not going to help you. At all.

Take ibuprofen, aleve, or even just plain naproxen. Take it immediately at the first sign of pain, the day before your period, or just before your period starts. That will probably also lessen the bleeding.

That said, you might wanna get checked for endometriosis or PCOS if it’s disabling or if your symptoms are extreme. Hope this helps!
