Irregular and heavy periods after Depo injections


Q: I was on the depo shot from ages 15-22. I never came on my cycle during this time. I am now 25 and, I cycle has been awkard since. I sometimes go without a cycle for week, even months. The longest would be 3months. When i finally would come back on it would last for about 3months and would be so heavy which affected my daily life. I have been hospitalized twice have fainted 3 times, seen 4 different doctors and nobody can give me any answers they just keep putting me on more birth control which i stopped. I wonted too know could this be caused by the depo shot ( wasn't every sexually active before, during, and after)?


A:   Depo-Provera can change a woman's periods when she starts receiving shots, though this should only last till the time the shots are given.  There are other causes of menstrual irregularities, and you should have a pelvic exam, pelvic ultrasound, thyroid and hormonal studies to rule out possibilities of polycystic ovarian syndrome, imbalance of hormones due to stress and thyroid issues.
