Nipple pain?

Hey guys ive been experiencing nipple pain for about a week now. This isnt ordinary nipple pain though! Like they STING. I barely could wipe them when I got out of the shower, soon as the towel touches them, it would sting. They are sooooo sensitive & painful. Like Yall🤦🏾‍♀️. They also seem to get hard and painful too! Anyone ever experience this? Did it turn out to be pregnancy?
