So my boyfriend I had sex about a week ago and the condom broke so we got a Next choice pill 2 days later which cost less then a Plan B pill. A day before we had sex I was on my period and I just started again a week later. I've also been sick for the past 5 days, today being the worse, I keep feeling like throwing up. Should I be worried or is this the side effect to the pill? Any advice will help
