Any other cronic worriers??

I had my BFP Monday 4 days before my period. Finally got to see  the words on a clear blue digital this morning. PREGNANT 1-2 WEEKS !! Why can't I relax! I'm always thinking of the next thing that might go wrong like a chem preg. I've taken about 10 tests hoping to see a darker line and if it's not, panicking. I only got my positive 2 days ago! have no solid reason to believe this pregnancy might not happen so why can I don't just accept it and stop worrying?? I'm on Google Constantly. Maybe it hasn't sunk in yet. It's almost like I have a gut feeling it may not happen. Maybe I need to delete my apps and ban myself from the Internet until I'm past this next 2 weeks.
