Am I pregnant or no??

So yesterday I took a test and got this...

After I took the test I wiped like a black discharge. I didnt think of taking a picture so I thought it was my period, so I put a pad on. After I got off work I barely had the black stuff on my pad. Well this morning I wiped a little bit of blood. But after that I put a pad and nothing is on it, and I'm not wiping blood anymore. I am currently 30 days late for my period. What should I do?

I took another test and it was negative. Not sure what to think.
