Conceiving after miscarriage

Hi all. I had a miscarriage 4 weeks ago. I had some slight spotting this weekend but really need a period to begin <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> again! What is everyone's experience with this and how long did it take you to get pregnant again? Wishing for a rainbow baby soon.... Thanks!
