So I am 16 years old, I am not sexually active but I have menoragghia so I got the depo shot to stop my periods. It worked but I gained more weight then expected. So in 2012 I switched to Implanon to stop my weight gain. The doctor told me I would not come on my periods and I would not gain weight. For a about a few months, that was true. Until I came on my period. I was on my period for 2 months with constant flow. She gave me medicine but that medicine made me come on heavier. So I stopped taking the medicine. After I stopped the medicine, I was off my period. It's been 3 months since this happened and now I am back on my period. I'm scared that it'll be longer then a regular period again. What can I do to stop my period?
