What’s going on??

So my fiancé and I were doing our thing and he noticed there was something coming out of my breast. Like a liquid. I went to the bathroom and checked and sure enough there is some milky white substance coming out.. I’m not sure what this means. I’ve taken two pregnancy tests, and I got very faint lines, by everyone keeps saying they are bad tests and are known to show false positives. I have no idea what’s happening and I’m so confused. Any ideas? Thoughts..?🧐🧐
