birth control
"I was on Depo for 13 years. Zero periods in that time. I did have a bone density scan after 10 years and that checked out fine. I went off of the shot one year ago. It took me about 6 months to get a period and now it seems my body is making up for 13 years of missed ones. I have had some serious hormonal swings over the past year but overall the period is the only thing I can see that is different. I am ready to go back on Depo until menopause."
