I think your doc just watches you more closely. He or she may send you for diff test to make sure baby is okay but i dont think they do anything else unless there is another prob
Once you reach a certain point in pregnancy your amniotic fluid does reach its maximum that it will be and that's normal. Is something wrong with your fluid?
What do you mean if it reaches a maximum? If your drs are concerned that you have a lot of fluid they may want to do some testing. Most of the time its benign but aomethimes there are problems that cause excess fluid
