Hello everyone! Girls, could anyone tell me if they've ever encountered or asked themselves this question: completely on the GYN, no monthly period. But there are moments when I feel like they're about to come - nervous, low stomach pulls. Could these be symptoms of menstruation, but not the actual ones? Or is it just my nerves going haywire ? One woman said that during menopause, such symptoms occur, but there aren't any. So I thought maybe it's similar here too ? Don't judge me harshly for asking, it might be stupid, but these are my thoughts ?
