Relactation?

Is it possible to start breastfeeding again? My baby girl is a month old and she's been having so much trouble with formula I really would like to try breastfeeding again(we had a lot of trouble when she was first born with latching, we later found out she had a tongue tie but by then my milk production was so low). My nipples are still leaking(sorry TMI!) but they definitely don't have much milk if any...
