Came off the pill 8 months ago as I wanted to give my body a rest. My period never started. I think it's down to me losing weight a couple of years ago. I'd lost nearly 3 stone - got down to about 8 stone for about a year but now my weight is up to 9 and 1/2 stone and steady. Want to start trying for a baby but despite being a healthy weight my periods haven't come back. Help!
