I went into preterm labor at 33 weeks without knowing I was having contractions. I had only dilated to 1cm with 40% effaced. Was put on restriction, I am not just hitting my 37 week mark. Been having Braxton hicks constantly last night they got stronger to where front of my pelvis hurt and low back hurt every time I got 1, they were also every 3 minutes. But they weren’t causing cervical change but I was 70% effaced now. So they said I wasn’t in labor. How can I know it’s true labor and it’s time to go back in? This is my first baby.
