First period since miscarriage..

I had a miscarriage at 5-6 weeks on 14/05/16 and I was and still am devastated.. but during the night last night I started my first period since the miscarriage.. I know it means that I'm ovulating normally again and that we can start trying for our rainbow baby but at the same time it's made me sad because I should be pregnant right now with our first child.. did anyone else feel like this?
