I think I might be pregnant.

A
So I took a test a couple of days ago with regular urine and it came out negative. The next morning I took it again and it came out with what looked like a faint positive. I took one again this morning and to the naked eye it looks negative, but I swear I can see a more faint line than yesterday's. (I'm probably just seeing what I want to see). 
I'm terrified at the idea of being pregnant. But honestly? I'm more terrified at the idea that I might not be.. :/
