should i tell my girlfriend i had chlamydia a year ago from my ex who cheated on me way before i ever even met her?

title. i’ve been dating my girlfriend for about a month now and it’s really good and me and her have been doing alot of reflecting of our past and telling each other things and this is one of those things ive thought of telling her but i am scared that it’s going to like scare her away from me and think i am disgusting? my ex cheated on me last year and the guy who she slept with, gave her chlamydia and then she had sex with me and gave it to me without telling me. I don’t have it anymore and i’ve been std/sti free for over a year.
