TMI beginning of yeast infection?

I’ve only had one yeast infection and it was a few years ago so I can’t really tell if I’m getting one or not but I have a burning sensation in my vagina and I don’t know why I did go tubing the other day I’m not sure if the water could’ve affected me in some way or not I haven’t had sex since I had my son so I know it’s nothing bad I just don’t know what is going on 🤦🏻‍♀️
