Preterm labor ?

Hi guys I just want to know if anyone has had a similar experience to mine. Yesterday I went to labor and delivery (33 weeks) bc I felt like I was peeing myself but wasn’t. Called my ob and she said to go in as it seemed like my fluids were leaking. I got to L&D and they said it didn’t look like I was leaking fluids but they did tell me I was having 3 contractions every 10 mins( I wasn’t feeling them) they gave me a shot in my arm to make them stop and apparently they did and they let me come home. My question is has anyone had something similar happen and if so if you have baby soon after ?
