How soon after a MC can you try again?

Im going through a miscarriage i was 4 weeks and 6 days when I started to bleed and was announce at the ER and my Hcg drop very quick. My husband and I were really ready for this little angel, because we were trying to get pregnant for 8 months but I leave everything on god's hand. I hope soon he will bless us with a healthy baby and deliver. But my question I how soon can we start trying again? I believe I'm emotionaly ready.
