i think i have a UTI

when i was twelve i used to get UTIS often... i think i have a UTI again. my vagina just hurts like not just when i’m peeing it’s no painful it’s just like stinging kinda... are there any at home remedies for a UTI... i also don’t want to tell my mom because i feel like she’ll know i’m having sex and i really don’t want her to know.
