four weeks and six days

Hey guys! I have never been pregnant before and according to the app I'm four weeks and six days, I don't go to the doctor until later this week for blood work. At four weeks I was feeling light cramps and twinges, now I don't feel anything. Is this normal?!?! Am I over analyzing it?!?! I'm away with my family and can't take a test to make sure. What was your experience in early pregnancy?
