Microgestin FE 1.5/30 and hormones

I was taking Ortho-Tricyclen low for a year and everything was fine. I had no side effects. Recently I told my doctor that I feel my hormones have gone down drastically and I haven't been in the romantic mood with my BF. I figured my daily routines may have changed something in my body. So she gave me 3 packs of Microgestin FE 1.5/30 and told me that would boost up my hormones A LOT. So far, after finishing the last pack, nothing. I mean NOTHING. All of a sudden I got the common cold perhaps the flu and now receiving lower back pain. The first night it was on the right only and now its only on the left side. Could this be a side effect to the pill???
