I have never missed a pill and I have been on birth control for 4 months then last Monday I woke up really sick. I was throwing up all day. I take the pill at 6:30 am every morning after taking it i threw up before 7 am and continuously threw up throughout the day. So I threw up the 9th pill of my 5th pack. The next day I was fine and took the 10th pill and i have continued to take the following pills everyday and I have not thrown up since. The next seven days my boyfriend and I used a condom but on the 8th day we didn't use protection. Am I safe? What are my chances of pregnancy? I am so scared.
