Pregnancy right after miscarriage?

Crystal✌ • Mother of 2 girls and 1 stepson. Trying to conceive our first child together. TTC since May.
I recently had a miscarriage 12/12/15 at 11weeks. The baby stopped growing at 8w 4days but didn't pass away until I was 10w 6 days. I started bleeding about a week later. It was absolutely devastating, we had been trying for almost a year to get pregnant. About 10days after I started bleeding and everything was complete me and my fiance started having unprotected sex again. I'm wondering how soon can you get pregnant after a miscarriage? Or if we should have waited longer?
