Nipple pain?

Melissa
So this is my fourth pregnancy, I'm 17+1 and this is a totally new symptom to me. My nipples feel sore and sensitive all the time. It feels like when you first start breastfeeding or when a guy gets a little too excited about sucking on them. Lol. Even showering is uncomfortable. Would it be weird to use lanolin while I'm pregnant? Any other suggestions?
