My husband and I had our first

on January 2nd. They had me do a 2nd shot of HCG on the 7th. I go in for official blood work on Thursday the 17th but I got this positive test this morning! Do you think it could still be leftover HCG or am I really...?

Edit: I tested again this morning, expecting the line to be lighter but it was DARKER! I'm crossing my fingers for a BFP tomorrow with my beta test.
