Anyone else expienece Uterine irritability?

I am 27 weeks 2 days today. Second pregnancy. My first is just over 15 months. With my first I had prodromal labor at 37 weeks but thankfully didn’t have any complications or problems otherwise. Last week I started having some contractions and at first I thought they were just Braxton hicks but they started getting painful. They were irregular so I figured it wasn’t any kind of “real” labor but I called my OB. They had me go to L&D of course and I was told I had uterine irritability. I told them it felt just like my prodromal labor but she said this early there’s basically no such thing as prodromal labor, it would just still be classified as early labor. Thankfully everything was okay and baby was healthy so I got sent home. I’m drinking tons of water, over 120oz a day and keeping my bladder empty like they told me but I’m having some more of those painful contractions again. They’re still irregular but has anyone else experienced this? From what I’ve read this doesn’t make you anymore likely to go into early labor which is good but is this going to happen the whole rest of my pregnancy? Nothing really seems to help except they eventually pass a few hours after they start.
