7 1/2 weeks pregnant w/light spotting today and bad nausea and some dizziness...?

I have been very nauseous today and a bit dizzy at times. Last time I went to the bathroom, I noticed very light bleeding. The color is light pink (and not steadily occurring). I am not having any cramps or discomfort. I am wondering if it is coinsidental that I am nauseous today w/the spotting, or could this be something to be more concerned about?!
