What is wrong with me

Taken test but is neg but I️ feel pregnant and I️ don’t know what to do . My boobs look different my stomach feels weird looks bigger , I️ feel like I’m having stomach spasms and lots of discharge and I’m freaking out and almost in tears because I’m getting neg results but I️ feel like I️ am pregnant and I️ don’t know what to do

I️ spotted on the 18-20 on & off
