I took plan b on October 22 and my period came two weeks after that. The following month my period came on time and seemed normal. Then I had sex with my boyfriend on the 14th of December and only ONCE without a condom and he pulled out. Now my period is 6 days late. I haven't taken a test yet because I'm on vacation and can't tell anyone about this. Could I be pregnant?? Or the plan b freaking me out? I also have huge anxiety attacks and have been so stressed lately.
