Trying to get pregnant whilst breast feeding

Hi,

I am currently breastfeeding my 6 month old son and me and my partner are wanting to concieve another child as we would like them to be of simular age. I really don't want to stop breastfeeding but I have heard its alot harder to get pregnant whilst I'm breastfeeding however my son is feeding less due to me weaning him. I haven't had my first period yet so don't really know when or if I'm ovulating. Has anyone conceived whilst breastfeeding and how long did it take? Me and my husband don't live together so we don't have sex as often as we should. It took us over a year to concieve our first child.
