Nipple changes!

** I wasn’t sure where to post this, so sorry if this is the wrong group!! Let me know & ill delete it**

I’m due for my period today with no signs of it coming and have noticed a bit of nausea on and off the past week or so but nothing crazy but my biggest concern is that I normally have inverted nipples unless I’m cold or aroused (even then sometimes) but they’re both protruding now and noticing a couple dark blue veins around them. Anyone else experience this?? I’m trying not to get ahead of myself.
