BREAST DISCHARGE. HELP!!

Ladies! Today my husband and I were play wrestling. Nothing rough he was trying to just get the remote back from me. After we stopped I noticed a spot on my tank top. I check my nipple and it was wet. TMI, I squeezed it a little to see if it was really coming from me and it had a milky discharge. Im 4dpo and completely forgot about TTC for a minute. Is this normal??? Please help.
