Does BC hurt the immune system?

Hi, I looked around the site and could not find anything on this. I am just at the end of my first cycle of the pill (Yaz), and it seems like for this first month I have constantly been sick. Not really nausea or vomitting sick, but i have constantly had a cold, and right now it hurts my head when i move, my eyes and ears hurt, and i just don't feel well in general. In addition to that, my period has been EXTREMELY different, but i am not very worried about that at all.

This is odd to me because i normally really don't get sick ever. There are a lot of things that could be affecting it, such as stress level, but i was wondering: Is this kicked down immune system normal/common for the first month of taking the pill?
