should I go to the hospital? ??? I'm going to be a first time mom so I don't know anything . I experienced what I believe we're Braxton hicks contractions that were very uncomfortable accompanied by back pain durring them which was 6 times within 2 hours. I then took a nap an i just woke up with a dull ache in my lower back. should I go to the hospital to get checked or should I wait it out ? I'm almost 32 weeks.
