Hello. I'very been extremely regular for the past 5 months, but Ive had late periods before. I'm currently 10 days late for my period, and wasn't too concerned until today when I started throwing up for no reason. I had my typical PMS symptoms a week before I was due (cramps, backaches, and moodiness), and I still have them now along with the vomiting, headaches, and bloating. The HPTs I've taken have shown negative results. Is it still possible that I'm pregnant?
