Should I test again in a few days?

Leighton
My period was supposed to start today and I've had some cramps (not as many or as intensely as I normally do) these last few days but I woke up and... No period. I'm normally the girl who wakes up looking like Carrie (not really but you know what I mean) because my period almost always comes in the morning. So I decided to test since I was excited and my SO and I have been TTC.
The faint line showed up and I became confused. So I brought it to him and asked him what he saw (without mentioning that I thought there was a second line) and he said, "I'm not sure. That one line is really clear but the other isn't." So I know he sees it too.
What should I do?
