birth control period

So I've been on Junel for about a month and a half after being on lo loestrin fe. The first period on Junel came around and it was about the same amount as my normal period and I also had a lot of clots. It did last a shorter amount of time. However on loestrin my period was extremely light. I'm a little confused because I expected this period to be light but it wasn't. Could it be because I switched brands? Or should I wait till this cycles period before telling my doctor?
