11 weeks 4 days scan Q

My OB sent me to a fetal medicine specialist to get my NT scan. Everything was normal according to the sonogram however, he said he wanted to see me again in about 2 weeks for something different. He said that my baby's intestines can be seen outside his body at this stage -saying its completely normal at this stage and that I shouldn't worry at all- but would like to make sure they go inside his body in the next 2 weeks.
