Dr. Khurram Rehman
Fertility Medicine
In brief: Many possible causes
Not ovulating (releasing an egg) 'on time' makes your period late.
Causes include polycystic ovarian syndrome (pcos), underactive thyroid, excess prolactin hormone, aging of the ovary (diminished ovarian reserve), or low hormone levels (hypogonadism) from heavy exercise, eating disorders, or stress. See an ob/gyn for testing, or a reproductive endocrinology / infertility md if trying to conceive.
