First of all I wouldn't worry so much if I were you, stress makes your period even more late. I'm not sure if you can get the Plan B still, since your not sure if he comed in you but im pretty sure you still can. Never have sex with someone you don't know/ someone you don't trust especially if your drunk or your high because when they're supposed to pull out it literally can result in pregnancy but im pretty sure you know this already.
I wouldn't worry since you do remember you stopped. Get the plan B and good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
