I have never been a big person and have recently got married and now decided that I want to put weight on as I am only 7stone (height 5.3inch). Everyone is saying that I am now starting to look unhealthy. I am trying to eat bigger portions and more often but have only managed to put on a pound.

Also I am on the pill injection and always seem to have brown discharge is this anything to do with me being under weight??

Please help as I want to put weight on so I can start trying for a baby.
