How common is a miscarriage in the second trimester?

Im just wondering due to the fact that im between 13 and 14 weeks so i am in my second trimester. I had a miscarriage at 5 weeks so im very excited to have made it this far. How many of you ladies have had a miscarriage in their second trimester? Thanks for the help.

I'm due the 9th of september so am currently 15 weeks 1 day pregnant & worry about this too...It happens, but don't think about it. Think positive =)
