Has anyone gotten pregnant while breastfeeding? (Haven't gotten postpartum period yet)

My dd is 3 months old as of yesterday, still breastfeeding, and I still haven't gotten my period yet. I know that it's common to not get your period back while breastfeeding. Hubby and I have been withdrawing since becoming active again but yesterday he didn't. Just wondering how likely I am to get pregnant again since I haven't gotten my period yet. We'd like to wait a year until I get pregnant again but I wouldn't really care if I got pregnant now. I was just curious if anyone else got pregnant before getting their first post pardum period.
