Early contraction

So I went to my normal 32 week appointment, let my doctor know I’ve been cramping on and off since Sunday night and with the cramps I get a hard stomach. With my history on PPROM and having my son at 34+5 he did a cervical exam. My mommy gut knew something was happening, he did the exam and told me I’m 50% effaced and 1 cm dilated. Went to L&D and I was hooked up to the test and sure enough I am having regular contractions it seems like. So I go back tomorrow for my second steroid shot and for another NST. Won’t be long before baby girl is here going through all of this brings back so many scary things for me 🤦‍♀️
