Miscarriage

After 7 years of trying to become pregnant we finally did it!!! We were on top of the world excited. Unfortunately it was short lived. At 8 weeks and 3 days we suffered a miscarriage. (July 6th 2015) Dr of course doesnt have an answer as to why. My question is how long did it take to get pregnant after miscarriage. I'm still bleeding and have my follow up appointment Monday but just curious.
