So last AF showed up a little over a week ago.. It was a full blown heavy 5 day menstrual which was confusing to me because I had what I thought was my period 2 weeks before that. So that would make it 2 cycles in one month!? And now I've been experiencing for the last 2 weeks extreme nausea, retaining water in my legs and feet really bad, they ache and are swollen by the end of the day, backaches, dry nipples, sore breats, dizziness, I almost fainted at work the other day. Idk what's going on that would be causing all this. Should I bother with a test? Or just see me doctor?
