Am i having a cp?

So last Wednesday I realized I was a week late on my period so I took two pregnancy tests and had a faint positive on both. The next day I started a heavy period which lasted a full week. My period always starts out light then becomes heavy but this was heavy with clotting right from the beginning. I waited until I stopped bleeding and took a test and had a very very faint positive. Am I having a cp or could I still be pregnant?
