Somethings up

So I was two days late on period and only had pink spotting very small not much. Then I ended up starting it was just a pink color when I wiped no clotting no leg or breast pain just slight cramps. Then it began to look red and it was more of a watery consistency I had nights were I would wake up with blood on me. Everyone has told me sounds like a normal period so I waved it off it ended Thursday and Me and my boyfriend made up for lost time Saturday night. Sunday I get back home and when I was in the rest room I wiped and saw pink and pink discharge in the toilet. Today’s Monday and I’m still having this. Anyone else been through this? Could I have a infection? It doesn’t hurt when I pee, And I don’t have to pee constantly
