Hi, I've spoken with a nurse, but I always like to get second opinions. Me and my boyfriend had sex and the condom broke. Immediately afterwards, we went and purchased Plan B. My period was due to come on two days after we had sex which would have been May 19th. It is now May 23rd and I have yet to get my period. The nurse said since the pill is a hormone and since I was so close to my period coming that I may not have one at all this month. I was just wondering should I worry.

I don't have any different advice to give you. Should you worry? If you aren't trying to get pregnant yes, you should worry. There is no form of birth control that is 100% effective. You will have to wait to see if you get your period next month. If not, wait until it is 2 weeks late then test using firs morning urine.
