I read an article on how you can check if you have inverted nipples or not and so I squeezed my breast and this clear liquid came out. I tried it on the other breast and a white liquid came out. I had a small pregnancy scare a few weeks ago but I got a spotting period and a very faint negative pregnancy test. So I don't think I'm pregnant. My period is due next week could it be some random PMS thing? Advice would be great.
