Ugh, sorry to hear. Okay, weird question. Any chance you could have an old tampon in there? Check. You might as those are symptoms of it.
Maybe It is however my period stopped for one day and came back again after I tried searching for a tampon... but I’ve got an appointment with my doctor on Monday we will see what she says
Sweetheart, it is either a lost tampon or you have an infection. Bacterial vaginitis can smell like that. Please see your doctor really soon. You don't want an untended infection in that area.
