"can&#039;t use estrogen pills. this was my other option. periods varied from 3 days to 3 weeks. after suffering from horrible depression, weight gain, fatigue, nausea, constant breast tenderness, unpredictabe periods and constant spotting, dizziness, trouble sleeping, and cramping. after a year of hoping this would get better, the side effects continued getting worse. i chose to quit using the pills. i will no longer be putting hormones into my body."
