Bra size

Courtney

Okay tmi but I’m in a predicament. So I just had a baby 7 weeks ago and I am breastfeeding. I bought two nursing bras while I was pregnant. One is like an actual bra but it doesn’t fit my breastfeeding boobs and the other is just a thin bralette. Which works but I need more than one bra and would like to have one with some kind of support. Idk what size to go to. The bralette one is an XL and it fits in the cups but is a little snug in my ribs. The supportive bra is too tight in the boob area and hurts. Any suggestions would be great. Idk how to even measure.
