What is going on??!!!!

Okay please bear with me. Thursday night I posted on here about having contractions that were 3-5 minutes apart, lots of lower back pain, hip pain, and pressure low down in my pelvis. I called the doctor and she basically said there's nothing to worry about unless my water breaks or I start bleeding. Yesterday I was fine. But now today I have been experiencing what feels like I'm loosened up in my abdomen, vagina, and legs and I'm cramping a little like I'm bout to start my period. Plus I'm feeling really tired. On top of that I lost what appears to be a little of my mucus plug. I have an OB appointment Monday. Should I call back now or just wait until I see my doctor?
