How long did you wait to TTC after 13 week loss?

I've just recently had a loss at 13 weeks... Still bleeding from the miscarriage. I don't really know why I'm asking this already as I'm still deeply grieving. I guess its just making me feel a bit better to look to the future.. where hopefully I will have a healthy baby.

I will be asking my Dr. At my follow up appointment, but did you find it helpful to wait a few cycles to let your uterine lining build up? Or did you go for it right away?
