So a few days ago I noticed some yellowish discharge, but it comes and goes?And even when I get it it's just a tiny bit. I normally have discharge and stuff but I read that it's normal because sometimes when it gets exposed to air it turns yellowish. My vagina burns a little and it's itchy, and it almost feels like I'm going to start my period but I already had my period this month. I think it might be a yeast infection or bv.I'm scared to tell my mom because then she'll take me to the doctor and I'm scared that when they test me I'll have an std or something. I'm a virgin but my boyfriend and I do "stuff" and my mom doesn't know :/ What does it sound like? Any advice?
