Doctor Appointment for HCG test

I got my bfp today!!! Whoo Hooo! I called my doctor today to let them know and they want me to come in tomorrow for a pee test. I’m only 10-12 dpo. I expressed my concern with it being so early, i didn’t want a false negative on their test and the girl said it should show up. 🤷🏻‍♀️ I’m going to be heart broken if it’s negative even if it’s false negative.

What’s your experience with doctors pee test? Here’s my bfp I got this morning.
