Girls, I feel my stomach like it's period cramps all night... Today, all day since morning with intervals, it feels that way too... At first, weak now stronger, but everything is bearable. The plug has been gone for three days now after an examination at the doctor's office. I go to the toilet, there are clear discharge, but not much. Water hasn't come out. Should I wait until the pain gets worse or should I go to the maternity ward?
