Your history suggests a condition called "polycystic ovarian disease (or syndrome)" or "PCOS" , where ovulation is delayed or absent, allowing continual estrogen stimulation of the endometrium to occur with consequent limited "true" menstruation. Ask your gyn physician about ultrasound of your ovaries. If pregnancy is desired, ovulation induction may be required.
