Hello, please help. My fiancé and I had unprotected sex on Sunday.I was done with my birth control on Saturday so I was on the placebo pills. I've done some research and was told the placebo pills or that week still protects against pregnancy but I was very nervous. Since I was worried, I took plan B on Tuesday because we had no access to a pharmacy on Sunday or Monday. It is now Friday and I still haven't started my period. Should I be worried about being pregnant? Or does Plan B have some sort of effect on the situation? Again, I'm currently on the placebo pills and took Plan B and still no period. Please help. I'm sure what to do because I feel like Plan B would have pushed my period sooner or no? Please please help.

I'm kinding freaking out:/
Thank you so much!!
