Hello, I had unprotected sex with my boyfriend last night and I am wondering if I should take Plan B. I have been on a combination birth control pill since March, and have not missed a single pill in the last two months (and have been taking it around the same time every day-as early as 9pm and as late as midnight; but only ever a gap of 30 minutes to an hour of the time i took the night prior). I started spotting yesterday, and it was also the day of my first sugar pill (even though I was wanting to skip the sugar pill and continue with the next pack). I was sick last week and had slight diarrhea, but no vomiting. I am wondering if you recommend Plan B. Thank you
