Preterm labor

At only 29 weeks my tests for preterm labor came back positive. They did a swab in my vagina to test for the hormone. The nurses and doctor said that it means I'm at high risk for going into active preterm labor within the next two weeks. I got the steroid shot and they said I need to be on bedrest and sent me home since I'm not dilating. I have an ultrasound scheduled for Monday to make sure I'm not funneling from the inside. Anyone had a similar experience and baby end up making it okay? And how many weeks were you when it started and you had your baby? Thank you in advance for all who comment! 💕
