So I had a transvaginal ultrasound last week and it hurt alot we thought I probably had an allergic reaction to the lube they used. Well ever since then my vagina has been itchy and burns when I wipe it. Well I've had some like brownish discharge like when you're at the end of your period. Well I am on birth control. I have nexplanon. I haven't had my period for 2 years. Well today I went to go pee wiped, it burned then I saw this. What does that mean. I am 18 and live at home. Should I tell my mom and my doctor? Should I be concerned? Any one else have anything similar? Also I've been sick so I've been wearing my comfy underwear from Walmart lmao.
