Oligomenorrhoea – If you have irregular periods (periods that occur at the interval of 36 days or fewer than eight cycles per year), it could be a sign of anovulation
Amenorrhea – Although the criteria for amenorrhea is not clearly defined, females with no menses between 14 and 16 (primary amenorrhea) or menstruating women who experience the absence of periods for six months (secondary amenorrhea) are usually undergoing amenorrhea. This could also indicate your anovulation.
Anovulatory bleeding – If you experience anovulation, there could still be a build up of the uterine lining. Since there are no eggs to trigger the shedding, the uterine lining sheds randomly.
