The Pill

I just started on The Pill (BC) a couple days ago. The first day I took it, I felt slightly nauseous but nothing I couldn’t handle. Yesterday I took it on an empty stomach but quickly ate plenty of food afterwards. About 4 hours later I was completely sick. I puked all day and couldn’t keep anything down. Was my sickness solely because of an empty stomach? I’m scared to keep taking it if I’m going to puke everyday (all day) for the next 3 months. What’s your guy’s take?
