I’m scared

I know there’s many vaginal infections out there .. so I really don’t know cause many people are quick to say you have an std but sometimes it’s not the case but yea I’ve been having this weird smelly discharge sometimes fishy sometimes sour for years now but yea I’m going to the clinic with my mom in June to get tested for stds and hiv and I just hope the results don’t come back positive cause that would hurt me bad I just hope it was something else ! Pray for me guys!!.
