PRETERM LABOR! Help!

Nicole

I’m currently admitted into labor and delivery for regular every 2-4 minute contractions. Dilated to a 1. I’m 29 weeks tomorrow. I’ve received 3 of the injections they give to stop them and have no success. But dr said he will send home as long as they aren’t “regular”. So is it normal to be sent home still contracting but not frequent or regular? Any advice or experiences please share ladies thank you. I’m a worried sick mess.
