Is this normal?? 🤔

So it will be a year in may that I quit breastfeeding. My milk immediately dried up once I quit! I never leaked or anything. Today while I’m the shower I noticed little white spots so I squeezed my breast a little and y’all milk came out!!!! 🤯 is this normal?? We are trying to have another baby and yesterday I took a pregnancy test and nothing!! I am three days late, but my cycles are always a few days late..

*sidenote it’s not my first time seeing if there’s milk still*
