Okay so I'm a ftm and my ribs are killing me. My belly will tighten but no pain just slightly crampy? I don't know what contractions are suppose to feel like and other than my ribs hurting and slight cramping I feel absolutely nothing. I'm 39 weeks and 3 days 1cm dilated and 30% effaced as of last Wednesday.
