Getting Pregnant ASAP After Birth

L

I can only find information on if you AREN’T breastfeeding, that you can get pregnant about six weeks postpartum. But I can’t find anything on if you ARE breastfeeding (or pumping) when can you expect to ovulate again? I know every woman is different but I want an idea, do you ovulate six months later? A year? Or can you not ovulate until your breastmilk runs dry?
