Confuseddd

Okay so a couple days ago I went to the bathroom and I noticed my pee had light pink in it and it was on the toilet paper when I wiped. I’ve been antibiotics so I wasn’t sure if that was from the meds. I ignored it. Then since Friday I noticed I’ve had ALOT of white discharge where I’m wearing a liner. Today I had a lot of brown discharge. This was weird because I never get this a week before my period. Also, I’ve been cramping for over a week. Idk if anyone else has experienced this? I’m really confused😩
