Tmi period picture included

Andrea
The past 5 days i have been spotting and yesterday i wiped pinkish blood. But just now i went to the bathroom and founs this on my pad? It wasnt like this 2 hours ago. There was only one spot. And it looks black to me. And I've had cramping thats pretty bad. I also havent had a period since December. I took a few pregnancy test i got 2 negatives and a negative that turned postive with the dye after 20 minutes but it said dont read after ten minutes. Then i got a pink line going the wrong way on another tes it should of been 2 lines but the c line showed up horizontal and the test should of but it was verticle but didnt intercept. Im reallu worried what is this? And did my period start today or 5 days ago when the heavy spotting started? Or maybe yesterday when i wiped blood?
