I'm 11w5d with twins. Everytime I move a certain way or get up to fast (kinda like I'm stretching) I get a sharp pain in my lower abdomen on whatever side my body is pulling on. It hurts so bad and only lasts a few seconds. My first pregnancy wad a singleton and that has never happened the entire time I was carrying her. Is it normal? I have an appointment next week and I'm going to ask then.
