Positive pregnancy tests while on your period?

Mayce
This is currently happening with me and after doing some research online, it's clear to see that nobody really has any information on this. I don't really have anyone I can talk to about this so I figured I would post on here to hopefully give myself some insight as well as give insight to others. 
My story is that I had a dream that I was pregnant and decided to take a pregnancy test despite being on the beginning stages of my period. The test came out negative but after sitting out for a couple of hours a faint positive line began to develop. I have since taken 5 pregnancy tests, two different brands, 3 hCG inexpensive brand and 2 Clear Blue, and I am getting mixed signals and I can't find any answers and I'm not sure what to believe or what's going on with me. Maybe someone out here in this community of lovely ladies can help.
