With my first born I had horrible back labor and it started when I was 38.5 weeks I'm 35 weeks tomorrow and woke up this morning at 3:30am with horrible period cramps they went away after I drank some water but now their back and I'm nauseous. I'm just curious what you think, should I call my OB and ask them about it? I'm only asking bc I don't know what regular stomach labor feels like.
