labor?

I went to L&D; last weekend and they did some test because I was having a lot of pain. One of the tests showed that I shouldn't go into labor for at least another two weeks. This is is my first. most of the day I've been having lower abdominal pain and I'm not sure if its baby moving or what, but I feel my stomach tighten and it lasts for 30 seconds to a minute it still feels tight just not near as tight or hard. I'm not sure if it's just the baby or if I should be concerned
