I have been feeling like puking but never do. I have also had dull pain when anything touches my lower abdomen, even a seatbelt. I have had watery sometimes white discharge. I am on the pill and did miss it for 3 days at the end of may. I have been on the pill for almost a year and a half. What could be happening? I did take a hpt about 2 and a half weeks ago. It was negative. I have not had an actual period since January. I did have sex in that time period too.
