late period + started bc

this is my first month of birth control ever, in pill form & my period is only 1 day late which i'm not too worried about but could this affect when my period comes now? i have been having cramps, bloating, wanting to eat a lot, fatigue & sore boobs.. all of my signs but it hasn't come yet and it's been a couple days that i've had cramps. any idea or is it just the birth control? and i'm not sure that i even ovulated this month either. my discharge right now is thick and creamy white colored.
