Good night girls, today my stomach has been hurting all day under my ribs on the left side, probably because the baby is growing and pressing, just crap, I haven't eaten anything fatty, spicy or smoked, but I'm still in pain. Has anyone had this? Will it be like this until I give birth or could the baby be in such a position that it presses hard? I will call the doctor tomorrow, just can someone who has had this tell me what they did?
