anyone know what's happening??

Okay. So lately i have been having a lot of clear discharge and like some type of queefing? I don't know. And i have been peeing and dirt comes out? I don't know how to describe it but small bits of something come out. And tonight out of no where i have been receiving sharp cramps from the bottom part of my stomach all the way to my vagina and back. For right now they have calmed down but i don't know what this could be . My periods have been coming normally and i just ended mine like 2 days ago. Anyone know what this could be ?
