Hay naku, that's such a rollercoaster, four weeks ng uncertainty like that is emotionally draining talaga, kaya props sa strength mo at baby ninyo! The fact na umabot kayo safely sa 37 weeks with the bed rest and medication is honestly a blessing, at ngayon na nag-settle back to 3cm, at least may comfort na that window is getting safer. Keep monitoring those labor signs closely, pero breathe, you've made it to term na, which is huge. Praying for a smooth delivery for you and baby soon!
