I've been having contractions every 20-30 minutes since lunch, but they're so bearable that I can still walk around calmly. I just took a shower and didn't feel any contractions for almost 20 minutes or so, or maybe the shower relieved the pain, and I didn't feel it. The app sent me to the hospital twice ? But I don't want to go early, every day was training, and I think these will also be. Has anyone had this experience? The cervix is not receding, yesterday they looked at the chair and said the cervix is shortened but closed. Today my EDD is still.
