How long after mc can it take to get pregnant again

How long after early miscarriage can it take to get pregnant again? I was about 4/5 weeks when I miscarried 3 weeks ago today. I miscarried on the 8th and by the Monday pregnancy tests was back to negative

A week later I think i ovulated 15/16th as had camping and egg white cm but I also had the same cramp and egg white cm the start of this week too.

The last few days iv been feeling tired, boobs have started to hurt and still getting cramping what are the chances of getting pregnant so soon after?
