Based on the information i`ve given to my doctor he has worked out i am 7 weeks pregnant. This is my first so i`m unsure what is normal. My tummy has popped out and i can no longer fit in my clothes, extremely tired all the time, Ribs hurt, back aches, sore joints ( kness, ankles, elbows) Itchy back and tummy No morning sickness though .... but i`m only 7 weeks. Is it possible that we have miscalculated??
