Weird feeling down there

Gaby

This week I have been very dissatisfied down there , I get really itchy and have this weird white stuff, (looks a little like old milk and sticky) . I know for sure it’s not an std because I’ve only been with my daughters father and I get tested every now and then because you never know, but can it be a yeast infection? If so is there like anything I can take, this has never happened to me before
