I came off my pill a week ago and my period hasn't started. i took a pregnancy test which came back negative. what's wrong?

Your cycle will : Reset by itself after stopping the pill. Women have varying responses after discontinuance of bcp. Follow up with ur gyn for any concerns.Don't worry! http://www.Divinecaroline.Com/self/wellness/five-surprising-side-effects-going-birth-control.

Probably nothing: I assume you came off the pill at the end of the cycle. In that case your body will usually recycle within a month and everything should be fine. If it doesn't see a doctor.
