It pulls my lower back strongly, both when walking and resting, all symptoms like they're starting their period))) The due date is 39.4 days, this is the third time I think I'm going to give birth, but it feels like something new, as if I'm giving birth for the first time (the question is overused, but still) ??? ??‍♀️?
