Will it ever stop??

Tye
So today is my last day of week for of my first pack of pills. I had the weirdest experience of a period after being on the pill for the first time. So Sunday was my 1st day of week four and I started spotting, then on Monday the spotting got kinda heavier and there was brownish red color like how all my other periods start so I assumed my period had started but it was super light. The flow was heavy enough to not be considered spotting (at least I thought) but wasn't really heavy either so I thought it was the pill making my period lighter. So Monday-Wednesday was this light spotting but on Thursday it got super heavy and I got cramps and I guess this is my actual period. It's still heavy today, but when I start my 2nd pack of pills tomorrow will I stop bleeding then??
