ladies help! is it right?

So I'm in a medical assistant school and today I did a UA witch involved taking a preg test. I did this UA on myself. The preg test ended up showing up faint and then was pretty visible after 5 min. Doesn't look like anevap since it's pretty pink in color. In complete shock I took a second one and the same with that one.  I'm freaking out! So a class mate had a cheap brand one (stick one) I took that but that showed neg. now I'm confused... please help shed some light.
