Seasonique

I have been on seasonique for about 7 years or so. It was the only pill that wasn't giving me kidney infections every month. But for the past 2 months or so I have been spotting on and off and sometimes it's like I get my period, and it's worse than when I am actually supposed to. I have gone to the doctor, and it was almost a month ago. She did tests and had me go for blood tests and I haven't heard anything back. Has anyone else had any problems like this with this BCP???
