Positive HPT

After reviewing lots and lots of girls pictures of their pregnancy tests I've come to realize something.

I've been sexually active since I was 14. Without protection till 16. And back off bc at 17. So you can imagine how many pregnancy tests I've taken. Anyway. Every time a girl on here says is there a faint line? You all day yes and congrats. However, every single time I've taken a pregnancy test I've always gotten two faint lines. I've never been pregnant. So why do I get false positives every time?
