belly button pain

Hey ladies! So I'm about 5 weeks pregnant(not far along at all) and I've had belly button pain for a few day now. Not constant just sore feeling every now and then. Today I woke up and it had some liquid coming out and a small bit of crust. I cleaned it with a q tip and there was yellow on the tip mixed with a little blood. I called my dr and they have no earlier appointments before mine next Friday and said to clean with a saline solution. Has anyone else had this? Should I just keep cleaning it twice a day or make a trip to the er and see if they can maybe help me?
