Period life

I have been having cramps and also lower abdominal pain in my lower left area .what could it mean ? The app tells me that I’m high risk of getting pregnant. I took a couple pregnancy tests and they all came out negative. So what could my stomach pain be about ?🤷🏻‍♀️

it hurts like period cramps but less painful than real ones .

also have a red pink discharges when I pee and wipe down .
