starting back over

I breastfed my daughter all the way until she was about 7 weeks..and after that I felt as if I wasn't producing enough milk so I ended up just strictly formula feeding her which I saw she didn't really like as much.Shes currently 10weeks and 3 days now and I would love to start back breastfeeding her again if it's possible.Any advice on how I can start back up again without any issues???
