I don't know if I'm using the right flange
I'm currently using the Medela Motion inbra pumps (am getting a wall pump, it's arriving next week) and I can't see inside the pump super well, the only thing I can see is my nipple slightly and the milk flow.
I had my nipples measured by a lactation consultant and it came out to 13mm so I used a 15mm flange. Well I was pumping away a few days ago, noticed when I took the pump off I had some chaffing on my nip nops. So i grabbed my nipple measure and re measured (I waited until my nipples weren't swollen) I came out to 17mm so I looked up a guide online and it said I should use a 19mm flange. So I've been using that today but I think it's too big? I've noticed when I take the pump off my areola is really wet with breast milk, which is making me think it's pulling my areola in. I just don't know, and I can't see inside the pump to check.
