My sister should be 28 centimeters right now around her belly but at her doctor appointment she was 34 cent. instead the doctor is going to give her an ultra sound later next week because the size difference but everything seems fine and that its not her gaining weight. I was wondering if maybe she is even further than they think she is and is due alot sooner than her 2 origanal due dates. Is it possible for her to be due alot sooner than what the doctors think or is maybe the baby just really big? she just had her sugar test today so she is prolly like 7 months pregnant? The other day my mom told her she looked like she dropped but I couldnt tell and her belly button has been popped out for a few weeks also, im not sure if that means she might be having this baby even sooner or not...
