Leakage

Hello ladies so Friday night I took a shower and when I got out I noticed that my breast, idk, just looked different. I went to squeeze and some watered down milk liquid came out. It is from both breast and I did take a pregnancy test this morning and it was a BFN. I thought I saw a faint second line but my husband said it was just the pee line so idk.

I am on BC, I'm on the Paragard IUD so its non hormonal. Any advice from you lady's would be great :)
