See your ob-gyn. Especially if you have been inserting things into your vagina. you could certainly have an infection. If it progresses (such as from BV to pelvic inflammatory disease), it can affect your fertility in the future. So take it seriously. The ob-gyn will do some swabs and test you for BV, most likely, and will tell you what to do. If he or she prescribes an antibiotic, take it all, don't just stop when you feel better. If you don't have a gynecologist, see your regular doctor. But it sounds like time to get a gynecologist. And don't worry, the doc won't judge you.
