First yeast infection

I have never had a yeast infection before and I am currently self diagnosing. It started right after my period and I was using a new brand of baby wipe so I thought I was having a allergic reaction even though it was a fragrance free one. I had intense itching in the opening of my vagina and my anus that went away and came back intermittently also there’s an odor that I feel is strong. I don’t know if I should try to treat it or even if I should tell my boyfriend. Someone whose been through this help me please....
