Induce labour

My baby weighs 2.1kg at 33 weeks and was told that it will be difficult for me to deliver vaginally. My height is 147cm so gynae was concern of baby grow too big and risk of csect is high. I was told monitor my sugar level as well coz she suspected that I have gdm. So she mentioned if I have gdm she will prescribe medications that will help to slow down the rate of baby growth. If not by 40 weeks baby would have grown to 3.5kg and I wud have difficulty pushing. So my qn is, any mummies ever prescribed medication to slow down rate of growth of baby?
