I'm on cycle day 19. I usually have a 24 day cycle. I have been crampy and have had very sore nipples. I have been feeling a little queasy, not enough to throw up. It's just making my mouth salivate more if that makes sense? Is it too early to test? Glow says my period will not start until March 14.
