Contractions question


I’m 37w2d and went to L&D for decrease in movement. I got sent home because baby is moving fine, of course she started getting crazy in there once they threw monitors on me🙄 but I had high BP (which has been normal for the last two months) and I’m having contractions.

Now, here’s the question. I don’t feel the contractions so they weren’t concerned. Does this mean labor is near? How long could it take if I’m having them?

Sorry if this is a dumb question. FTM and have no idea how they work. I know the 5-1-1 rule though😂 but I can’t feel them so🤷🏻‍♀️
