I'm a repeat c section art for 39 weeks. I went into preterm labor at 34 weeks. I'm now 35 weeks and those contractions have never stopped. So my question is when I go in next week at 36 and they check me again and I'm dilated which I'm sure gas happen I losty plug today 😕 for the second time. At what cm dilated would an ob say yeah you know we need to set your surgery sooner? Anyone know?
