Is it normal?!

Hello ladies so, I’m 3 days late and have cramps and like watery discharge. Me and my sister were joking about me being pregnant, and she implanted the doubt on my head, so I took a home pregnancy test (Clear Blue) and it was positive 😱 but I’m still having cramps and the sensation that my period is going to start. I had a brownish sticky discharge too. Is this normal? Am I pregnant or not?! Help
