testing out trigger shot

Brittany💚💛 • I'm 26 years old from New York. I'm currently pregnant with boy/girl twins! 💚💛Due December 2015!
Has anyone tested out the trigger shot and the lines get darker? I'm 10 dpo and trying to figure out if the lines are a true postive or if there is a possibility of it still being a false positive. It's not drastic, but they are clearly darker. Bottom two are this morning and the top 3 and the three days previous. (7dpo, 8dpo, and 9dpo)
