Anyone else do this? also. question

I swear i get so anxious when i know i’ll be ovulating soon, i rest all different times of the day, i have insomnia , i just took a opk at 2:30 in the morning 🤦🏼‍♀️ i think i’m driving myself nuts, but i know i can’t be the only one who does this.. & why does it say not to use your first morning pee?
