Moms who pump and supplement.

Emma • I`m Emma. I`m 23 and happily married to the love of my life. We welcomed a baby boy 5/13/16 by emergency c-section!
Hey ladies. I'm a ftm and I'm faced with the possibility of having to stop breastfeeding due to a posterior tongue tie which makes it extremely painful to bf even with a shield.  We have an appointment with pediatric dentist tomorrow but my lactation consultant said that it's not a guarantee it will fix my pain issue.  
So that leaves me with a few options. 1) Continue breastfeeding through the pain and cause my nipples further nerve damage.  2) pump exclusively and hope I don't have to supplement 3) pump on a more relaxed schedule and supplement. 
I'm leaning towards 3 as a plan b if I have to stop breastfeeding.  Are any of you moms pump and supplementers? Tips? Tricks to keep supply up? What formula did your little ones take to the best? Any help is appreciated!
