I know this is going to sound really really really bad but I took a Plan B pill December 2014 then I took another one February 2015. March 2015 was the last time I had a period until today! I started crying in the bathroom lol I don't know if it was exciting or just plain crutial evil tears.. But I'm happy I got it. I'm glad my ovaries are working! I know I should've gone to the doctor but I was to afraid of hearing some horrible news, after all I'm 20yrs old. I'm now on birth control and I hope to never take that pill. I honestly don't recommend it now.
