I got mine in when i was 20 and two years later got it taken out to start for a family.

I found that I put on at least 40kg with it, now I am also finding I have lack of energy, sex drive and my mood swings are still bad.

The Depo injection sounds good, but if you want her to go on the Pill then just remind her every night, make sure she has it at dinner time etc... that way you can monitor it.

I started the Pill when I was 14 as I had bad periods and I found even though I thought I would forget it, after the first month I became more confident in remembering...
