Please help...

I took a test yesterday and my mom thinks there was a slight positive on it. Then I took 2 this morning and I thought I saw something and then it disappeared. Then I took 2 at about 2 and one if them definitely had a line at about 5 minutes maybe 1 or 2 minutes after. What should I make of this?? I don't know what to think. I'm 4 days late today with cramps....
