Lines still not getting darker

Hi ladies I found out I was pregnant 4 days ago now. Of course I am being a fruit loop testing like a crazy woman non stop! I have already had 2 chemicals already. My lines don't seem to be getting any darker. But they don't seem to be getting lighter unless I test during the day. And my clearblue is popping up pregnant 1-2 still. I should be about 3 weeks and 5 days today according to my LMP and when I ovulated. I have been having light cramping also that seems like my period is going to come. What do you ladies think? I can't get to the doctor for blood testing till Friday. Xoxo
