Im on the birth control Cryselle and I have been on it for about 5 months and last month I had my period for a day and this month I have not got it and I was suppose to start my period wed. and today is when I start the new pack, also took two pregnancys tests which came out negative so I don't know what to do

I don't think there's anything else for you to do except wait and see if you get your period. Cryselle is not 100% effective (but I'm sure you know that).
