Irregular 😔😰

Hey!!!!! So I have been having irregular periods since I was 11 and it would always be 3-4 months behind and

my mom says it’s normal bc it happened to her at tht age and my doctor says tht it’s bc I’m a broader line diabetic but I don’t think thts the problem since I lost about 46lbs. If u have any idea whts going on plz comment below!!!!!!
