Yes, the depo. I used to be on it and I can't remember how long it took for my periods to return to normal, I do remember they said upto two years, but mine wasn't anything like that. She's not that worried, but just wondered what other's experiences are.
it was about 3 months for me and then it didnt stop for a month, I am now on the implant that last for three years which has a lot less of the hormone and also as a bonus stops your periods and your are fertile as soon as it comes out!!
