I'm 24w4d and for the last hour and half I've been having mild period pains accompanied by back ache and tightenings low down. The pains aren't painful but they are enough for me to stop what I'm doing. There every 2-10 minutes but only last a few seconds whereas the back pain lasts a few minutes. I remember my daughters labour and it started off similar to this.
Should I wait and see what happens or should I contact MW for advice
