Pumping is not nearly as effective as nursing. What may be best for you is to spend some time at least a few days (2 weeks + is better) devoted to only you and baby. Hold baby skin to skin as much as possible. Nurse on demand and offer even when it isn't demanded. During this time you want to offer the breast every time baby as much as whimpers. Even if baby suckles than a minute and stops it will stimulate your breasts to want to produce milk, of course the longer and more often he nurses the better.
Also you need to RELAX you may be slowing your flow by stressing. Try mediatation, yoga, massage and relaxing baths. If dh/so is there take baby in the tub with you and nurse while you both relax. Finally if baby is having about 8 wet diapers in 24 hours, he's probably getting enough.
Hope that helps.
