line after 10 minutes

Holly
Help!! I took a test before my shower. AF was due this morning.  After 3 minutes I swear I saw a faint line but it looked more like an indention.  At 10 minutes I see a faint line with color. Are the 10 minute results ineffective because it was outside 3 minutes?
Update!!!  BFP today!!! To the dr in the morning.  Only 2 weeks along is my guess so terrified I could lose it
