Disappearing symptoms

Hi ladies, would love your advice as I am going crazy wihh worry... I had all my pregnancy symptoms disappear abruptly last Thursday after feeling completely debilitated on Tuesday and Wednesday. Prior to that have had the extreme exhaustion and tender breasts. As of this weekend, I feel like everything has heavily subsided. I am only 7w and won't have my OB appointment until 10w. :( i know I can't worry but am really hoping it is not a missed miscarriage. Anyone feeling similarly?
