First, i would like to mention that i am on Depo. I have had 3 shots so far. I finally stopped spotting like a month ago. The other day my boyfriend and I had sex, which is not a rare thing. The next day I started spotting again. Not only am I spotting, but there's an odd odor. This is so awkward and it's making me not want to have sex which sucks. There's no burning or anything, so i'm pretty sure it's not BV or a yeast infection. Any help is apreciated.
