I spot during my periods and sometimes i wont get them?

Irregular bleeding: Irregular bleeding (sometimes called dysfunctional uterine bleeding) is very common. Many different things can cause it, from growths in the uterus (fibroids/polyps) to missed/delayed ovulation. An examination, sometimes with blood testing is done to evaluate and plan possible treatment. Sometimes a change in medications (like ocps) are in order.

Get checked.: Reasons for irregularity include weight gain or loss, breastfeeding, alcohol use, eating disorders, marked emotional stress, endometriosis, uterine fibroids, cervical polyps, polycystic ovarian syndrome, excessive exercise & pregnancy. When a girl has just started menstruating & around the time of menopause periods can be irregular.
