Labor?

Jo

So apparently very few pregnant women actually notice when they lose their mucous plug, and only 15% of women actually have their water noticeably break before going into labor. I am 37 weeks pregnant with my first and I know nothing! I was up nearly all night with what I hope was Braxton Hicks contractions. I have noticed no extra discharge Or mucous. How can I know when it is Braxton Hicks and when I should go to the hospital?
