Nipple discharge normal?

Alaina

So my husband and I have been trying to have a baby for the past year and half, and the last couple months we have been doing the whatever happens happens method simply to help with the stress of always seeing a no. I believe my period is due tomorrow.... now I have no idea what possessed me to do this it was almost like something internally guided me (I know sounds crazy. Iv been laying around all day and my ac is acting up so it pretty hot as I live in Texas so Iv been sweating on and off today. I decide to clean myself up noticing I was sliding around in that area lol. And something told me to check my nipple when I looked down I noticed a little bit of a fluid pooled in the center. At first I figured it was sweet to I wiped up but then my interested like sparked and I lightly squeezed it and more fluid came out, about the amount of a drop of water from a water droplet, it freaked me out as I never had that happen.so I check my other one and it did the same thing. At first the fluid was clear like with a tiny bit of yellow tint and then had a little bit of green. I read on line it’s normal to experience, clear, yellow, white or green discharge. And one reason could be a early pregnancy symptom. I’m scared cause I don’t know if my body is telling me something is wrong or maybe telling me something is right...

after that I immediately took a hcg test and it was negative. So has anyone experienced this and then found out they were pregnant?
