how do you plan a wedding and get over a lost of of your unborn child?

I just found out on fri that I'm having a misscarrage(because i havent full lost the cells so the doc's call having) Well we are getting married in 41 days and for the past few days I dont feel like doing any wedding stuff and every time I try to sit down and do something I change my mind... I havent want to come on to tell anyone on here... so has this ever happen to anyone els??? If it did what did you do get over it????
