Is it normal to be this irregular?
So I've gotten my period when i was 14 going on 15 and It's always been irregular. By irregular i mean, at first, i would be only a month late. Gradually that increased to about 2 months late, then to 3. And it has always been that way. Expect one time last year, i was 5 almost 6 months late. But now i'm back to it being 2 months late. SO my question is; is this normal? Oh and i'm eighteen years old. I've never gotten a checkup or anything because my mom insisted it was only lack of vitamins.
