Is this normal?

My LMP was 03/26/2021. Yesterday (04/16/2021) I was at work and started to feel cramps then went to the restroom and had bright pink/watery discharge then got extremely hot to the point I thought I was going to faint... My periods are spot on every month, I don’t get cramps and never spot almost a week and a half before them.. today I am feeling super nauseous and light brown discharge.. has anyone else experienced this before? I’m confused as to what is going on with me when this is out of character for my body... any insight/help would be greatly appreciated!
