Plan B
"It was a heat of the moment thing and we went unprotected. Not too smart, but it happens. Took Plan B One Step less than an hour later. Like you, I was anxious and jumped into reading reviews and began the waiting game. The second day I felt dizzy, nauseated, and sleepy, but it didn't kill me. For those wondering,I'm 5'3, 145 lbs, and never took birth control before. Just relax, even if you don't feel it, this is working. Easier said than done, I know. My period came a few days earlier than expected and heavier, but I've never been so happy to see it!"
