Help advice so needed please 35+3 weeks pregnant advice

Hi guys so when I was 32+2 I went for my growth scan and next thing i new I was getting a swab test done to see if I was at risk for preterm labour which it came back positive so after nearly a full week in hospital with nothing happening and 2 steroid injections later I was discharged.. now I'm 35+3 and yesterday I went for a etg think that's what it was called it picked up contractions which I barely felt bare the pressure feelings I was getting due to babys head being down urine tests done had little mucus plug in it so had to wait for a doctor for an examination which stated I was 1cm dilated... so I'm guessing that could be why I was so sore on Monday as I was close to going to the hospital but all pains past until late yesterday afternoon I did go 4 weeks early in my last pregnancy so was just wondering what experiences u ladies went thru if use had a baby during the 35th week are my baby's lungs ok if she was to be born now... and I no nothing and have been told nothing about antenatal care units (nicu) stay for a baby born that week any experiences or advice would be great to put my mind at rest on any type of outcome baby may be born with
