?? Can anyone explain this ?? Please

AF DUE TODAY!!!

.mild cramps here and there

.I had sore boobs and nipples really sore but seems to have calmed down

.tired a lot but some days I’m ok

.nausea 3-4 days ago but had subsided

.very WET discharge and pink spotting

(I normally get pink spotting around my AF but nevertheless I have never had excess CM!)

I tested 3days ago and negative??

I’m not sure when I ovulated ?? I will attach the chart in the comments.
