My last NORMAL period was aug 30. I always have had very heavy periods (around 3 days) even after being on birth control for a year. the last two months my periods are just basically spotting and only a day or two. I know your period can gradually get shorter over time but this happend so suddenly. I have a bad habbit of starting my new pack of pills late. I took a test two days ago and it was negitive. Ihave been nauseous alot, but im hypoglycemic so this happens at times. Should I be worried at all?
