Hmmm....well, I am done with my AF now, it started off like really watery brown cm for one day, not a whole lot at all.
The next day it turned super dark brown cm, I thought I saw some dark red on the tampon.
Then AF full on started the 3rd day. Darker than usual. This was a weird AF.
I usually get some kind of nausea around AF time...but the purple nipple thing is weird...if you have some cheapies around I would test...
