Vagina Problems

At least once a month I've had a UTI, an irritated vulva, some recent back pain, or like at the current moment, a UTI with back pain and constipation. I'm wondering if it has something to do with my birth control since it's been happening since I started it? The first and only time I went to my gynecologist for the irritation, they didn't find anything, and it developed into bacterial vaginosis. I'm thinking about going to the clinic today so I can clear up my current mess soon, but any thoughts?
