Is it okay to miss a period when you change Birth control pills? Is it normal? Do i need to take a test? I just recently changed and now i've finished my first month of the new pill but have not had a period yet- and i have not missed a pill! IS this normal? I really need some advice!!

Yes, it's OK to skip a period when switching brands.
However, I'd still recommend that you take a pregnancy test just to be sure.
