Burning...

Okay so for the past hour it felt like my 😻 is burning 😩 Idk why....I washed up with olay and never had a problem EVER.....My mom says it could be my period coming but i highly doubt that its irregular.....She told me to soak in a hot bath when i get off work (In 5 hours) Im drinking a cranberry juice as we speak....Should i douche when i get home ?
