possible twins??

Hi, I am seeking any help from mummys who have carried twins... I have twins in my mother's side and my father's side, and very distant with my partners side, but I'm almost 8 weeks pregnant and I already can feel slight flutters and movements in my stomach , and I am pretty sure I'm already getting a bump! I have had my daughter and with my pregnancy with her I didn't show until about 5 months , I never felt sick , but this pregnancy I am constantly feeling nauseous and have been put off all foods! and I can't even manage eating a full meal without feeling like I'm going to puke 😦 my back and sides have been aching like mad aswell !! can people please tell me how they felt and went though with twin pregnancies
