My daughter was preterm at 27 weeks, at 35 weeks diagnosed with a kidney stone, had a stent put in. She is now 36+5 , in constant pain in lower front for days. Is the pain from the stent or labor or what? At 27 weeks, dilated to 3. Last checked 70% and at a 3 1/2 dilation. Her first childbirth, she didn t feel contractions, until in the hosp. and also when she was having contractions with the pregnancy also.
