It might not hurt to time your contractions and see if there is a regular pattern. Also, chart the level of pain on a scale of 1-10. If there is a consistant, progressive patterns or the pains get worse I would definately give the doctor a call. Of course, if you are worried, I would call anyway. :) If you feel like you need to go to the hospital, go! Don't feel bad for being concerned. You're a mom, it comes naturally!
