period or not

I'm not supposed to have my period for another week or two, but I seem to be having some light, and light colored bleeding. I've been nauseous, but people in my house have been sick. Should I be worried that pregnancy is a possibility at this point? I really hope not, but I'm a bit freaked. When I was with my son, my MIL said "You better not be pregnant! Just wait!" My angel baby, my husband was like "Are you sure you're not pregnant? I think so" Then the other day out of no where, my friend was like "I had a dream you were pregnant, and the last time I had that dream was with my baby's momma, and she was pregnant with my daughter", so I swear I'll kick his ass if I am. I must be like super cursed or something.... If you had slight bleeding, how was it?
