I'm sorry, OP. It sounds like it's very individual. For my miscarriage at 10 weeks, I got my period 35 days later. I am not sure I ovulated that cycle, though, and the period was very light. And that was 4 months ago and I'm still not pregnant despite trying every cycle.
I'd say if you don't get it back in another 2-3 weeks, check in with your doctor. You could also try fertility acupuncture to jump start it -- that's what I've decided to try to regulate my cycle. I haven't been at it yet long enough to know if it works, though.
