Not sure what's going on

Hi all! So this is my second month on the pill and today will be my 3rd brown pill I need to take. My problem is that I haven't bled yet. Not even a little bit and I really don't know why. One of my friends told me last month that it'll take a few months to regulate. But last month I had a little bit of blood the whole time I was on the brown pills. If anyone could give me some reassurance or advice it'd be much appreciated! Thanks!
