Pregnant?

Hi everyone,

I need help seeing if I'm pregnant. I had a really really light positive pregnancy test. I am afraid because I've been spotting on and off for the past almost 2 weeks now. If I am pregnant should I be worried about the bleeding? I would bleed for about 3 or 4 days straight and then it would stop and now it just started again. I'm going to take another pregnancy test soon since this one was so light, but could that bleeding be implantation bleeding or something? Please help.
