Need some reassurance

I am 4 +6 today and have absolutely no symptoms besides a missed period. Had some bloating earlier in the week but nothing now. No cramping, no painful breasts, no morning sickness, no fatigue, no bloating. I know I should probably be thankful but I can't help worrying if everything is all right. It's my first pregnancy so I have no idea what to expect. Only going for a scan at 8 weeks. Is this normal?
