Yeast infection?

Okay so I have some slight itching and burning on my labia minora and have woken up two mornings due to the discomfort. When I go back to sleep and wake up it's hardly noticeable. There is very slight bleeding but it's possible that it's because I've taken my birth control a little all over the place. I'm on both bc pills and an iud so I'm ruling out pregnancy. I had a lot of sex this weekend so I'm not sure if there's just some small tears that I should let heal or if it could be a yeast infection. Anyone have an idea?
