Okay my period is 5 days late and I've been having some light brown discharge most of it is just on the toilet paper and I put on a pad so it don't get on my panties and it's just a little spot on the pad,I had the brown discharge for 3 days,  I'm 5 days late and AF is no where to be seen. Is this a good sign? Should I test and see if I may be pregnant? Would I even have a chance of being pregnant? Thanks!
