Nipple on fire

I woke up in the middle of night with fairly intense pain in my left nipple. It was burning and stinging and a cold washcloth made it feel a little better. I’ve never felt anything like it.

Today it’s still really sensitive and my bra is so uncomfortable.

I mentioned it to a coworker and she said it’s my milk coming in.

Already? I’m almost 14 weeks.

Anyone else ever have this?
