It's possible

First response will pick up very low amounts of hcg - sometimes as low as 2 and 5 and under us normal resting hcg levels. Your levels should double every 48 hours so if the line is staying the same faint line then it's probably not a positive result. If the line darkens over a day or two then your levels are rising and you should get another blood draw to verify. Good luck to you!
