TMI but help?!

My nipple has this dry/flaky like skin that falls out when touched. It looks like it’s my nipple but it’s not if that makes any sense? Does anyone know what it is. I woke up this morning and only one of my nipples has this dry, flaky skin that falls out of the nipple when i touch it. I just reached 14 weeks and this literally started today. What’s is it?
