I have always been a safe person when I comes to sex. I am on birth control and always ALWAYS use a condom. Me and my partner  were having sex and when he pulled out, he notice that the condom may have broke because of the extra white fluid on the outside. We checked the condom and found it didn't break. Could that fluid have been mine? So I went and got plan b right away because a week before I accidentally missed a pill. The only thing is my period was supposed to start 2 days after the day we had sex/taking plan b. Is that messing up my period? I am on day 3 of my placebo pills and still no period. I took a test just to make sure on day 2 of placebo pills but it was negative. Should I worry? Any advice would be great
