I'm 36 weeks pregnant. I breastfed my first child for 17 months with no problems in the nipple area. I noticed last night that one of my nipples has a red place on it that is possibly a sore. I think if I were to mess with it, it would probably bleed. That breast is also a little sore. Does anyone have any idea why this would be happening and what I can do about it? Now I'm worried I'll have problems nursing this one since this has happened before he's even born.
