BREASTFEEDING AND TTC, please help me

kam • ...because He loved us first.

So I’m 5 days late on AF.... I’m breastfeeding my 11mo son and the last few days my breasts just feel more full and like they’ve gotten bigger. My nipples sort of burn when he nursed. Never felt this before, does this sound like a pregnancy sign? My question is, how many breastfeeding mommas while pregnant, felt these or similar changes I their breasts? Or what changes did you feel?
