IV’s during unmedicated birth?

So I plan to go completely natural and unmedicated with my labor (praying I can do it lol) but I’m wondering since I’m not planning on getting any type of meds can I tell them I don’t want an IV unless absolutely necessary later on? They are super uncomfortable for me and I’ve done a ton of research about going unmedicated, they all say you will progress much better and faster the more relaxed and comfortable you are so I feel it will interfere with my relaxation and make my progression more difficult if they force me to get one right away for no reason. Obviously I will ask my DR but just wanted to see if anyone had any insight for me on here.
