Are women who are petite/skinny more likely to have irregular periods than average or heavier women? - irregular periods more condition_symptoms

I am 19 years old, 5 feet tall and weighs 95 pounds. I also go cycles that about 34-36 days, and sometimes my periods are even later. I know, wear other things, the irregular cycles and normal weight can, however, has nothing to do with it? (One of the nurses I work with once told me that he will be) So I have to, look what other people think, too.
Thank you a bunch!
