help!!

So my vag has been super itchy lately, but like the lower part, not really around my labia or anything..just near my butthole and vag.... my mom told me to clean it with witch hazel (organic no alcohol) and that helps soothe it and cream helps sometimes too... I'm pretty certain it's a yeast infection..I've been super stressed lately and take birth control which affects my hormones. I'm just wondering if anyone else has had the same symptoms and what they used to treat! Thank you
