Hello girls, I'm 40 weeks and 2 days pregnant. The mucus plug isn't coming out. Since yesterday, the lower abdomen has been dulling and pulling every 15 minutes, but sometimes it's quiet. Has anyone experienced this? It seems like the beginning of real contractions, or false ones?? I really want to give birth already, maybe is there something that can help start labor? Give me some advice please.
