is there a second line? HELP!!

my period was supposed to arrive on Thanksgiving. so I figured I'd wait a few days even though this app has been pretty accurate. the only time it hasn't been accurate is when my period arrived a day or two early.

so I took a test this morning. when I went to wipe I noticed some blood. so I thought oh it came and I just wasted time taking a test. went to get ready and realized I hadn't thrown out the test. so when I went to throw it out I looked at just out of curiosity. and noticed it looked like there was a very faint second line.

I need help figuring out if I'm actually seeing it or not. this is the first time taking a test so soon. when I found out I was pregnant with my son 7 years ago I was further along than I thought so the second line really showed up.
