38 +4 impatient!

I'm physically feeling ok but mentally I'm struggling! My son was born at 38 weeks exactly. This pregnancy at my 36 and a half weeks they checked and told me I was 3cm dilated 75% effaced...I got so excited thinking this baby would be born at 38 too weeks or even before. Ever since I've over analyzed every single symptom! Now I feel like this baby will be on time or late. They definitely come when they're ready! I'm just anxious bc I teach kindergarten and I've been ready to be done with work and I'm working until she comes! Come on baby girl!!!!!!!!!!
