My sister switched from Seasonle to Lo - and was spotting (heavy-ish like you described) for a month, until her body acclamated to the Lo... You're probably going through that - especially with the increase in appetite, etc...
FYI, I was on Seasonale & loved it for 3 years, no symptoms, THEN, for some reason after 3 years I started to get really weird side effects & went back to OrthoTriCyclen.
Good luck!
