I'm currently 35 weeks with my first, this morning I passed a large amount of clear mucousy discharge and what followed can only be described as strong period pain in irregular waves, and not always with tightenings like during previous braxton hicks. My friends who have recently had babies tell me not to worry but I can't help but feel something isn't right, it's been going on for about 4 hours now, not sure if this is just wishful thinking though!
