NEED HELP

E💓

So I am on the pill for my period as they were really irregular, I’d get my period like 2/3 times a month.. and I’ve been on the pill just about 5 months now... pretty much I got my period about 10 days ago and everything was grand then on Saturday I was getting really bad cramps, it continued on to Sunday but I also felt sick on Sunday I saw something on my knickers it was like “discharge” but a funkyyyy colour it was like white, brown and red and i was like wtf and then today cramps and nausea continued and then I got the “discharge” again but it’s more red then white/brown. I’m so confused and idk what’s wrong🤷🏻‍♀️🤷🏻‍♀️ can anyone help?
