I had sex with my boyfriend but I was protected sex but I didn't want to take a risk so I took a Plan B and 5 days later I was bleeding was that my period or could I be pregnant?
If sperm (cum) or pre-ejaculatory fluid (pre-cum) came into contact with your vagina, then you could still become pregnant as Plan B is less reliable than regular hormonal birth control.
Plan B is a huge dose of artificial hormone for your body to deal with. It's meant for total emergencies for this reason.
Plan B can make your periods irregular for some time, & can cause bleeding before your period, or you could have none for a while. However, everyone is affected differently, so it's impossible to know how it will effect you & whether bleeding was your true period or not.
My advice is to do a pregnancy test when your period would normally be starting.
Plan B works by delaying your ovulation until the sperm leaves your body (up to 5 days or so in some women). If you are already ovulating (fertile) when you have sex, then Plan B can't do that, so you'd need one of the other methods of emergency contraception; either the other emergency pill called Ulipristal Acetate or to have an IUD fitted by a doctor within 120 hours/5 days of the unprotected sex.
