Am I pregnant?

Ok ladies, I have some questions for you. This is my second month ttc. I have been taking pregnancy tests every morning for the past few days and they are all negative. I felt a bit dizzy today when I was out shopping, but it wasn't so bad that I had to sit down. As soon as I got in the car it seemed to diminish. Today I had an increase in creamy cm. Which I feel is unusual for me since I think that I usually get more of a watery discharge right before my period. But I am not entirely sure as I don't always look super close to cm before period. This morning I took a hpt that was the cheap one from Wal-Mart and when I look at it it sort of looks like there is an extremely faint line. Like you have to keep tilting it to see it. Does this sound like I could be pregnant? Period due in two days. And is it possible for an hpt to be so faint you can barely see it?
