Is this normal???

So I went for my 38 week appointment and the doctor checked me and told me I was still closed. Then I went to stand up and noticed that I had clear liquid running down my leg so I called the doctor back in and he did a full exam and determined it wasn't my water. Since then however I have been having the worst cramps of my life and (tmi sorry) but the intense urge like I have to poop but nothing happens. Is this normal? Has anyone else experienced this before?
