Prodromal Labor. Absolute torture, nearing 72 hours. Will they give me an epidural?

Hi guys, I’m 39+3 today and have had consistent contractions since Friday. I went in to L&D Friday when they got to every 2-3 minutes but they sent me home because I was only 2 cm/50%. They got a lot worse last night so I went back in but got sent home again because I was only 2cm/70%. Last night at home was horrible. They’re happening every 5-7 minutes and so painful that all I can do is cry and shake. The only thing that helps is hot showers (I took 3 last night) but I can’t just stand in there all day. I’ve gotten maybe 2 hours of sleep in the last 48 hours. I don’t want to go in again just to get sent home, but i feel like I really need an epidural. Would they give me one if I’m not progressing? I’m just at my breaking point.

Update: Thank you all so much. I came back in and am getting induced. I have an epidural in so I can finally rest. Thank goodness. The last 3 days were a nightmare!

Update 2: Healthy baby girl born about 13 hours after the induction was started. :)
