I am religious with taking my birth control pills but somehow skipped a day. I took two when I noticed (the one I missed plus the one for that day) but because of the fire alarm being pulled in my building I took both 10 min later than I typically would have. I’m almost at the end of my second row. My long distance boyfriend is coming up tomorrow for 4 days and we never use condoms. Should I take a plan B pill after having sex the first time? Am I protected still since I missed one pill (even though it was ten minutes late)? What if we have sex multiple times over the next four days, will a plan b cover all of them?
