No worry! mine also has this when she was week 16, but it was disappeared during week 2x. Have consulted a lot of doctors, but they said it is very common nowadays without any reason. Some said it may related to the 'drome' or whatever. I haven't taken any further test and keep worrying until deliver. Fortunately, thanks God, my bb has found no problem so far and she is quite active and lovely.
If you feel uncomfortable, you can take further test. Although many doctors said no worry, but my worry still carry on till delivery and sometimes I hope I have done the test.
