Seasonique/Daysee

I’m on my full second pack of this (6 months).. at the end of the first pack I had massive spotting, bleeding, etc for a couple of weeks. I’m on my period pills now (but these still have a low dose of estrogen).. I’ve been on them for 5 days now and no period, just a little spotting when I wipe periodically. I have been having some cramping and headaches, but no other symptoms. Pregnancy tests are negative. Do you all think it’s just my system adjusting to the BC?
