ending progesterone shots

Ciara
So I've decided to end my progesterone shots after this week. I'll be 32 weeks next week and that's when I had my first daughter. Anyone else stop early? What reasons? I personally feel like they have caused my irritable uteru and I my lifestyle 9 years ago was total polar to now where I'm settled and not doing as much to cause preterm labor bc they don't know why I had my daughter early. I'm not dialated even though baby is head down in my cervix...
