Okay so I missed two days of my birth control , and the third day I thought if I take all three I'll be okay right? No. Wrong. That night I felt more nauseous than ever and I had a huge migraine. Then I woke up at 5am throwing up everything in my stomach. I would wake up every hour that day and throw up , anything I drank or ate just kept coming back up. I learned to take my pills on time all the time because I was miserable.
