I use to get antsy on milestones too. Not that I got too far anyway. But still I did. I dont know why. So now I dont count days. I dont even know when I stopped. I just know a round about time frame.
I stopped counting for that very reason. It was stressful for me and added more pressure.
I think its great that you are being active and doing things to keep you occupied. That helps a great deal IMO.
Hang in there. Your doing good.
