38 недель, раскрытие 2–3 см, отошла пробка: что значит, что врач прощупывает плодный пузырь?

I’m 38 weeks, 2cm dilated almost to 3 and had a second membrane sweep today. i lost my plug with a tinge of blood this morning (before my sweep which wasn’t done until almost 5pm) and at the doctors she said she could feel my water bag. i should’ve asked but was too excited, what does that mean?? im really praying babygirl comes on her own so i don’t have to get induced!
