Hello, I started having contractions five days ago and my cervix is thinning. Yesterday evening, contractions began and stopped, and today they're starting again like that. Contractions are ongoing, but I feel them only when lying down, such as cramps as during menstruation. When I walk or sit, it doesn't really hurt, and even just the stomach quiets down and everything. Are these training contractions? I'm already 40.6 weeks pregnant.
