"i&#039;ve been on this for 1 1/3 months (switched from depo shot) and i&#039;m not sure i like this when i started it just 9 days in i got my period and at the end of the pack i didn&#039;t get a period and now i&#039;m on week 3 of my second pack and no period like last month. so i&#039;m a little worried and i get headaches a lot and my breasts hurt (this just started a week ago). if by the end of this pack i don&#039;t get my period then i&#039;m going to the doctor."
