My period is 2 days late I have been vomiting for feeling like im going to on and off all week my breast were sore for a couple days like they normally get before I start but then it stopped. It's weird because there is so much cm I keep thinking ive started but haven't I'm unsure if I should take a test because the past 3 months if me and my so have sex to close to my period its either a day late or a day early I normally have a 25 day cycle and its currently day 27 I don't know what to do.
