midgut hernia

So we went and had a scan yesterday. Baby measuring a few days ahead of schedule(was 10w 2d, baby measured 10w 5d) strong heartbeat and moving all over. The u/s tech said she did notice a midgut hernia and that it could be totally normal at this point, but it was a little more pronounced than other ones that she sees so she is having us come back in a few weeks to make sure that it has resolved. Has anyone else had this or heard of it before?
