Birth Control question!

Home More advice Health

So I've been on birth control for about 2 and a half years, but about 3 months ago I switched over the a new brand. (not really relavent but oh well)... My periods are super irregular so my packs don't always match up.....my period always exceeds the 5 placebo pills, or I have to go a week or 2 into the next pack before I get my next period. MY QUESTION IS: if my packs don't match up, then does the birth control still work?!
