alright so I've already had my period at the beginning of this month but while I was on my period I had a uti & I had to take medication for it she also gave me yeast infection prevention pills, but my discharge is watery & light brown/yellow tint and according to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> my next period is in 5 days... could this be a sign of my period coming, could it just be because of the medication, should I go back to the doctor????
