B.H.
I was enormous like just enormous. I don't remember how big I was but before pregnancy double d's after my milk came in I swear I was like g's or something. We had to go to a specialty store to find nursing bra's big enough. Anyways I had a preemie and the size of my preemie with the size of my breasts was just to drastic and as much as tried I couldn't breastfeed my child I would suffocate my daughter and it was just to awkward. So I pumped for awhile and eventually gave up. My back hurts normally from being bigger breasted but with breast feeding and the size they became it was untolerable unbearble. I wish you luck your not the only one with this problem.
