I have never had an issue with having an unusual odor in my vaginal area until I took the shot, it is making me very self conscious. I am do for my 2nd shot and wondering if I should continue this type of birth control or stop it all together. Will this go away or is this going to be an issue as long as I am on the shot? I am 42 years old and believe it or not this is the first time ever using birth control so I have nothing to compare it with. My doctor informed me that this would be the best type of birth control for my age and the fact that I am a smoker.
