I put on 10kg when I moved in with DH when we were younger. I gradually put it on over the years too. The 3 months before wedding I lost 7kg and was almost at risk of not fitting my dress!!
Since wedding I've put on about 15kg !!!! In just one year!!!!! Do working hard to get those 15 off and back to where I was, before bub. The rest I will tackle after had bub when I have baby weight to move as well.
