Now i am experiencing a metallic taste at the back of my mouth and i am freaking out because i obviously don't want to be pregnant.I also know that i have to wait 2 weeks to do a pregnancy test but i can't take the paranoia and fear.I feel like i am going to have a nervous break down before the two weeks are up.I am resentful of my boyfriend even though i know it was an accident.What are the chances that i am NOT pregnant??
