The pill symptoms

So a few days ago, I woke up with brown spotting and just thought this was normal as I'm getting used to the pill. A few days later, more and more blood is appearing and now I'm basically on my period and I'm experiencing cramps and everything else I always get when I'm on my period. I only had my period about two weeks ago and now I have it again. Is this just normal as I'm getting used to the pill? Pleaseeee help me!!
