Welcome! Yes, so many encouraging stories and women to draw from on this site. I was put on bed rest at 22 weeks due to a rapidly shortening cervix of 1.8cm and am now approaching 30 weeks! I am also on prog sups and have been having bracton hicks fairly frequently. I've been told to stay hydrated and lay on my left side to help with those. Many women have made it full term with similar situations. I am pregnant with twins so I have extra pressure on my cervix and thought Id never make it to 30 weeks 8 weeks ago. You can certainly have hope of making it much further.
To keep myself busy I read a lot (avoiding Google bc it terrified me when I read too many bad stories), I blog to keep record of everything we are going through in this journey and enjoy visits from friends and family. Music and prayer keep me sane when I'm overthinking things and overwhelmed by it all. Like you, I am focusing on my weekly milestones and notice how quickly the weeks have passed when I look back and see how far I've come. Wishing you all the best!!
