I have been on my period for 20 days and i was given cyklokapron which hasn't stopped the blood flow. this has never happened before in my 35 years of life?

Irregular menstrual periods are common. The fluctuations of estrogen and progesterone can be easily affected by pregnancy, stress, weight gain/loss, lack of sleep, exercise, thyroid problems, and uterine issues such as adenomyosis, polyps or fibroids. If your irregular bleeding persists, talk to your Dr about your irregular periods and what testing can be done to determine the cause.
