I had unprotected sex on Saturday, April 24th, went out and bought Plan B the next day. I was relieved when I got what I though was my period 5 days after taking Plan B. Now I am reading about breakthrough bleeding and am scared that was not my actual period. I have such a crazy busy life I can't remember when I actually was suppose to have it. So now I've been nauseas and dizzy for the last couple days and am freaking out that I may be pregnant! It's probably too soon for me to take a pregnancy test :(
