29 weeks newly diagnosed dexcom vs regular meter

I just got my appointment set up to meet with a dietician with maternal fetal next week. They sent in testing supplies to have me start testing four times a day. I’m absolutely terrified of sticking my finger and asked if I could get a dexcom as I’m not confident I will be able to do it 4 times a day. The nurse shot me down basically said that I can get the dexcom but I’d still need to stick my finger 4 times a day as the dexcom is not approved for GD and results might not be accurate enough yet. Which might be the case but isn’t that better than nothing? Has anyone else used the dexcom exclusively or a combination of dexcom and regular meter? I’m just so upset over this whole situation and I haven’t even been seen yet.

UPDATE: I just did my first finger stick and I had to do it twice because I waited too long and the meter turned off and I also didn’t place my droplet correctly. Second stick on my middle finger hurt more than my index but overall I feel a little better about doing it going forward. My read was 101 after dinner.
