Late period!!

Alyssa

I’m freaking out. I’m 17 and I had my period for maybe 5 years? I’m fairly regular, I get my period when I’m predicted to or within a day or two. Well, I have only started to become sexually active since like last month (and I don’t have a TON of sex either) and it’s always with protection, I never let him do it without a condom. I had sex last Tuesday, and I was predicted to have my period maybe Friday? I didn’t get it and I freaked out and bought Plan B and took it on Sunday (5 days later) and I still have no period! I haven’t bought a pregnancy test because I’m so embarrassed and I live in a small town but I’m also so desperate to know whats going on. Please, if anyone knows if this is normal or what could possibly he going on tell me! If it helps, we used Durex condoms
