My period is a couple days late. I took a pregnancy test today around 1pm. I had drank a lot of juice but also had been holding my pee. I’ve had a lot of watery discharge, but no period. I’ve thought I started my period because of how wet it was down there, but no - just discharge. Is the pregnancy test wrong? Should I test again? Am I likely not pregnant? I don't know why my period is late, please help.
