Yes normal. Mine have been doing that for a while sometimes my bras will be wet or my pj shirt. With out any stimulation. I'm 33weeks now but it started a while ago
Yes I noticed mine leaking around 21 weeks. Completely normal. And don't worry your not going to be going into preterm labor just from squeezing your nipples just to see if anything comes out. I noticed that at night time or after the shower they leak more then during the day.
Yes it's normal and it takes hours and hours of nipple stimulation to cause contractions. Otherwise how would people nurse older babies through pregnancy??
Y would you pinch your nips ? Just letting you know playing with your nips can make you go into preterm labor so be careful
