I took Plan B 5 times in the course of maybe 3 weeks after the condom kept breaking and my boyfriend ejaculated in me. I was supposed to get my period around October 12-16 but it's October 30 and I still don't have it. I took Plan B on October 5, 10, 13, 19, and 27. Am I not getting my period on time because I took plan B so close together so many times? When should my period arrive?
