I guess I just don't understand how the one month that I don't get my bc and have sex 1 time using a method that only has a 4% chance of failure results in this! What kind of odds is that?!

My bf is convinced that I'm giving myself a hysterical pregnancy because I'm certain I am and that my symptoms are caused by myself being anxious about it which is very possible. I'm going to the school nurse tomorrow that way my mom doesn't receive a bill in the mail from insurance and start questioning me.
