birth control
"I'm 34 years old. First period was at 9 yrs old. By 15 my periods were pain filled and I was diagnosed with cysts on my ovaries. Birth control was prescribed. Fast forward through a pregnancy and more ovary issues, January of 2012 I had the Implanon put in. life was fantastic. Not one period until December 2014 , a couple of months before I was due to have the replacement put in. Nexplanon implanted early February and life went on! 

July of 2015 was my first "double period" month. August and September were the same so I visited the doctor where I heard "irregular bleeding was normal and was put on estrogen. No periods for October. November -2 periods, now they are happening every other week!! 

No explanation!!"
