Nipple Discharge?

Hunter • 27, married, 2 fur babies 🐶🐶, and had baby girl 3/6/19❤️

I’m currently 4 DPO and experiencing nipple discharge that I’ve never had in my life. I came across it after it had already dried but it was kind of a white color. I know we’re all analyzing everything our bodies do at this point to get answers but has anyone else had this in the tww and were pregnant?
