Stopped breastfeeding.. period?

So its been 4weeks that i stopped breastfeeding. My son is 6months. He did nurse just before bed time but i never felt a letdown tho. He stopped nursing complety for almost 2weeks now and i still haven't gotten my period. I do stil have milk when i sqeez my boobs (really hard) but its very little. It doesnt leak at all like it used to. How soon after stopped breastfeeding did you ladies get your period?
