I have been taking birth control pills for about 7 months, I was suffering from side effects lately and I decided to stop taking the pill on the 7th day of the new pack. It is now 3 days later and I have started to bleed, is this normal? And for how long will this last? Also I forgot to take the pill 2 days before I stopped so I took two in one day and got really sick and threw up I was also sexually active that same day, the next day I did not take the pill, could I be pregnant?
