Irregular periods: Irregular menstrual periods are common. The fluctuations of estrogen and progesterone can be easily affected by stress, weight gain/loss, thyroid problems, and uterine issues such as adenomyosis or fibroids. If the symptoms persist, talk to your Dr about your irregular periods and what testing can be done to determine the cause. if you are sexually active use contraception.
