Why are my nipples so sore?

emma

I’ve been breastfeeding my little one for over 4 months now, and for about a week now my nipples have been so sore. Like I can’t even touch them.

I know my period is late but that’s normal for breastfeeding. But I have all the cramps and symptoms for my period. But the one that’s getting me is that my nipples really hurt. It hurts to nurse. Please help
