Plan B

Alainna • In between knowing what I want and having absolutely no idea which direction to go...adulting 😊
Hello :) 
  So I took a Plan B pill on Sunday (May 7th) because I had sex when I was ovulating (not the best idea). I took the pill within 36 hours like the directions told me to. Fast forward to today: my boobs have been hurting so bad 😫 and I've been cramping like crazy. Is this normal? I've read reviews and women have said that the symptoms only last for 24 hours but it's been 4 days and counting.
