This is my 2nd month on birth control and the first day of my inactive pills i had brown/red blood that's very light, is this normal? is it my period?

Yes: The week of inactive pills should trigger a period, often lighter than periods without OCP's

Birth control pills: Today's bcp's are very low in hormones, and on the inactive pills bleeding does occur but is very mild and much lighter than a "normal" (non-bcp). The low hormone levels of the active pills allow very little growth of the lining of the womb, hence there is very little bleeding with a "pill period" which you are having now.
