You can relacatate or even induce lactation if you've never had kids. Relactation can take a lot of work. The sooner it was that you breastfed, the easier it will be. I highly recommend the link above to kellymom.com. Also, look into La Leche League, they are an international breastfeeding support group that hosts monthly meetings, all free.
The first step will be to pump as often as you can, even though nothing comes out. This will start to stimulate milk production. Also try herbs like fenugreek to encourage supply. If you can, get a supplemental nursing system, this feeds baby formula from a tube while they are latched to the breast.
HTH, good luck!
