Anyone ever have discharge from nipples?

Jessica

I am trying to conceive in my 30s. I’m 37 and I’m a few days from period with some breast swelling, twinges and stomach twinges a little lower back pain as well. Today I was checking my breasts and I gently squeezed and saw clear liquid coming out of nipple. Is this normal? Anyone get this too? I had sex on my fertile days but think I’m out due early negative pregnancy test before my period.
