Garam

So I have been on the pill since the 13th of August (I started taking the pill as I started my period), and during my first month, I did bleed quite a bit. And I stopped taking my pills (my inactive days) Which I got my period during my inactive days, as soon as 7 days were over, I stared my pill right away (and I haven't missed a single one) then I've been spotting here and there, and yesterday and today - I've been bleeding heavy like I'm on my period! And I have mild cramp, is this normal?? Someone PLEASE HELP!
