Any day??

So last night I went to ER thinking it was officially time for baby to come (39weeks5days) had contractions for 10 hours starting 30 min apart and went to hospital when they were 5-10 minutes apart only for them to tell me I'm only 3 cm and since I'm small I'm thinking I'm having contractions which are really brax hicks. Which I know they weren't. I'm just wondering if it was false labor and if it was should I be expecting him to come any moment?! Help ftm here 😕
