Hello everyone! Describe how your labor began, what contractions are like, what they're associated with, at what frequency and duration they were, and how they changed, did you expel water, a plug, thank you so much ?? The fact that something is unclear, there's tension and pain like when you walk for a long time and your back hurts, only on both sides, I don't understand if it's contractions or not
