Labor at 28 weeks and 2 days

Yesterday I woke up with Braxton Hicks we’re it was tightening in lower abdomen but than went too my back I drank some water and went back too bed I woke up and like every morning make breakfast for my son clean and went too the bathroom I lost some of my mucus plug I was still having Braxton Hicks so I laid down and just relaxed with drinking water. Around 4 I went to the er because there was more that 7 in a hour when I went too labor and delivery they gave me a shot too stop my contractions and monitored baby girl she was fine moving around like crazy about 2 hours later my contractions came back they were 8-10 min apart having back contractions as well they gave me another shot too stop the contractions they checked my cervix and said it’s thinning and soft

Has anyone experienced this and deliver past 37 weeks? I’ve been put on bed rest should I get some preemie clothes just in case and prepare too for into labor soon?
