Hi everyone! I'm 34 weeks and had just gotten my Nuby electric breast pump and I was super curious so decided to give it a wee go and see what it felt like. I used the stimulation then it went onto expression and it felt horrible! Pretty painful! I continued for about a minute and it never got any better. Will it feel better when there's milk? A tiny bit of yellow stuff came out but not enough to get into the bottle should I be worried about that? My breast have not leaked before and it hasn't since.
