Girls, please tell me I can't understand, it has been painful for three nights now, my stomach hurts, then my lower back hurts, before that, I was helped by a pad, but now my lower back hurts at 3 am, still hurts, but at the same time my stomach pulls, probably once an hour, what could this be? It seems like I should go home, maybe too early.
