How long after a miscarriage...

How long after a miscarriage did it take you to get pregnant? 
I started having my miscarriage the 30th of September, I'm not sure exactly which day it completed but by October 9th, I had a negative hpt result. I read it can take anywhere from 2-4 weeks to ovulate. My husband and I haven't been using any form of birth control and I'm just wondering when would be ideal to test to get an acurate result?
