Pregnancy questions.!! Test questions.!

I took a test and It came out positive then I started bleeding. Not heavy enough to wear anything but not light enough to go unnoticed. I took a test during the bleeding and it came out with a very very very very faint line(If you zoom in you can see it). (The third one). The bleeding has stopped but I still have some cramps and my breasts are sore. Some one pleaseeee tell me what's going on or at least try and explain.!​
