2 Month Old Fussing while latching

My sweet girl and I have had a bumpy BF journey. At the start she just wouldn’t want to latch on to my right breast because my nipple is slightly inverted and sits lower. After two weeks she got the hang of it and everything was great up until about a week ago. Shes fussing at the right side again is only wanting to latch on it every other feed and even then still fusses.

We were told she’s doing purple crying by our ped but they didn’t say anything about the fussy nursing. I’m getting worried my supply on the right side will drop I usually pump 2-3oz max it’s the slacker boob/side.

Is this normal at 2 month? Should I contact the LC at my peds office to talk about it!?
