Questions about birth control, pease help?

I would talk to my gyno and proboly will tomarrow but i'm wondering if any of you can answer my questions first. Im not sexually active i'm just taking BC to help control my horrible cramps and also to be prepared for whenever i do start having sex. anyways i started taking my pill at the wrong time, i guess i was suppose to start it right after my period but i started it at the first of the month because thats what my friend told me to do, anyways so i messed that up, also i'm not very consistant with what time i take my pill, its usually around 10 or 11 but sometimes not unti 12 or 1 am, will this matter, that my hours arent consistant? also i forgot to take it last night for the first time so i took them both now, but i only have 1 white pill left until i have the brown ones and im suppose to start my period, considering all the things i messed up my first month should i expect my period to be messed up? also if i'm better at when i take it with the next packet should i be concerned about if i'm well protected or not?
