Constant irregular contractions

Has anyone ever experience consistently irregular contractions? I was admitted into the hospital for 4 days in pre term labor. Thankfully I was able to be stopped and my contractions lightened up. I am 4cm dilated and 75% effaced. For the past two days My contractions have been back. I’ve been keeping track of them and sometimes they’re 3-5 min apart, then go to being 10-15 min apart and sometimes I can go a an hour and only have 2-3 contractions. It’s driving me insane because I don’t want to go back to the hospital until they are closer together and more consistent. But I’m curious if anyone else has experienced this? Any sudden movement, standing up walking up stairs I instantly start getting a contraction.

It has been quite the week! This is my first pregnancy and I’m 34 weeks pregnant. Opinions?
