When to conceive again after a miscarriage?

I had my first pregancy and miscarried on January 31. I was 8 weeks and it was very traumatic for both my husband and I.
I just wondered what advice or experience anyone's had when they have begun trying to conceive again after a miscarriage. My Dr says physically my body is ready as I've had a period since but I've heard mixed stories that you're likely to miscarry again if you fall pregnant too soon. Any feedback from someone that's gone through this too would really be appreciated.
