Am I wrong

I recently just suffered from a miscarriage on 9/11 at 7 weeks pregnant. I break down in tears very often, I don't want to get out of bed or eat even...but now my mind has been obsessed with weddings in the last few days. I feel guilty & sad that I'm even focusing on a wedding when I just lost my baby, deep down inside I feel like how can I plan a wedding that my baby was supposed to be here for.
