I'm 14 weeks pregnant today, and for the past several days I have been noticing my nipples have a different shape... as in the shape of a baby's mouth. Anybody who has breastfed should know what I'm taking about. I don't recall this with any of my other pregnancies. My breasts haven't changed in size or weight yet. Just the shape of the nipples have changed. I find it absolutely strange. Are my nipples remembering breastfeeding a baby or what?!
