What is going on!?

So, af started 7/10 (a day early) but it was weird... It was bright red a couple times, but mostly darker like oldish blood, there were a couple clots, but not like normal. Normally I have horrible back pain and cramping, so bad I typically end up sweating in a ball on the floor until meds kick in, and even then I don't feel well for about 2 days, Friday was nothing like that. I was even able to have sex the first day (with no mess even) which never happens. By Saturday no more clots, and never filled a pad. Typically my flow is bad for the first day. By Saturday it was dark maroonish and basically spotting and by Sunday nothing. It's Tuesday not and Wil I'm still spotting a little (only when I wipe) its just brownish black and mixed with egg white cm. I thought it's was really weird, and I still have sore breasts and I'm getting strange pinching cramps so I took a test this morning just to ease my mind. This is what I got, do you see a line? Has anyone had this happen?
