Feel free to tell me I'm delusional

I am really confused.

On Wednesday morning my temp dropped way down and I started bleeding. So, my period, right? It wasn't that heavy, but it was red blood. Then yesterday, on what I thought was CD 2, my temp went sky high - from 96.81 to 98.34. I took it about 75 minutes later than usual, though, and I'd had a few glasses of wine, so I figured it was a fluke.

Then yesterday I noticed that the bleeding had gotten much lighter, instead of heavy like it usually does, and that my nipples had started to hurt, which isnt usually a period symptom for me, but which did happen before I tested positive with Joseph. I still didn't think that much of it, until this morning - my temp was still up. I took it at the usual time and had no wine last night and it was lower than yesterday (97.71), but still higher than my highest temp before the bleeding started, and well above the coverline.

So just out of curiosity, I took one of the cheapy pregnancy tests I got with my OPKs. And there's a line...I think? It's really faint. I've never used these tests before so I don't know if they give evaporation lines, but whatever this is came up within the time limit.

It's only been 11 days since I ovulated. Oh, and the bleeding is still lighter today - there's still occasional red when I wipe, but nothing on the pad all night.

This has got to be some kind of chemical pregnancy, right? If that was even a line at all? With Joseph I used a First Response test, so I know what a real line looks like on one of those. Should I try one when I get to work? Should I wait a few days and see what happens? Should I call the doctor?

Whatever's going on, I don't have a good feeling about it. Red blood = bad.

Edit: It's 9 AM. I just took a First Response. The second line came up immediately. No mistake.

But this has to be chemical, right?
