I think it means the amniotic sac is coming out of your cervix a little bit
I was like this at 38+3, I had my little girl at 38+4. I was 6cm before I felt any contractions. Bulging waters is a good thing, just means your baby is on their way down which causes your waters to bulge and get ready to break. Good luck!!
Thanks ladies! I'm hoping I go tonight! Going to hit my hubby up for sex lmao well see.
