Another period?

So I started my new pack of pills and then I went out of town and forgot them. So when I got home at I took the ones I missed and the one for that day so Thursday,Friday and Saturday. Well Sunday morning I woke up and had brown blood as of it was my period. And it’s been over a week and it’s still happening! I’ve continued to take my pills like usual I thought that would stop the bleeding but it hasn’t. Does anyone know what I should do!?! Am I supposed to just let it happen until I get my real period again when I get to my last week of pills or do I take my week of period pills?!? Does the bleeding ever stop? Help!
