Sounds like it! Probiotics and cutting down on sugar (by a LOT) will help ...
Birth control pills and IUDs make you more susceptible to them because they throw off your trace mineral balance and there a lot of diet factors and stress factors as well. Make sure that you're using unscented for everything that contacts that area and I would encourage you to do more research beyond the over culture treatments of it as they don't deal with the root causes at all, they merely mask them. You can treat it naturally with plain yogurt and even a clove of peeled garlic if it's a bad case - put them on (yogurt) and in (both) your vagina and wear a pad...Do your own research, of course.
Best of luck!
