Could be... It could be that your progesterone levels are low, and prolactin levels are high. When was your last period? And have you had intercourse recently? Anytime you're not pregnant or breastfeeding and you have discharge out of your breasts you need to get it examined by a Dr. That is one of the signs to look out for when you do a self breast exam. would I worry, nope! But just make sure to get seen if you're not pregnant.
Yes, it is possible because there could have been a problem with tubal. When in doubt, take a pregnancy test
