Paranoid πŸ™„πŸ˜πŸ™„πŸ˜

Kourtnie β€’ 18 years old πŸ‘‘ expecting my 1st in October 2017 πŸ€°πŸ’•
So I am almost 6 weeks pregnant, confirmed by my doctor. The only symptoms I'm having is extremely sore boobs & headaches, oh and cravings, but for some reason I can't shake the thought of having a false positive by the test and the doctors. I don't have morning sickness, and it's too early for the heartbeat. Has anyone else had this fear?Β
