Boobs don’t leak. Normal?

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​I am almost due and nothing has leaked from my breasts. My fiancé said to try to stimulate my breasts by pumping for a few seconds. When I did this is what came out. Only came out from the left boob. Is this normal? FTM
