Cramping/abdominal pain

This is my first post-so bare with me. I ovulated last week and am not expecting my period for 12 days (I have a long cycle), but I have been experiencing pregnancy symptoms (tender nipples, nausea, etc), but for the past two days I've had pain and cramping on only one side of my lower abdomen. I'm concerned about ectopic pregnancy, but feel it's way too early to go to the doc because it's way too early for even a pregnancy test. Would this pain be possible for a normal pregnancy, or can it only really mean bad things? Does anyone have recommendations/suggestions? Thanks!
