nervous. 14 weeks and spotting!
Spotting could be really normal, but it could also mean something is wrong. Only a doctor can determine that. If I were you I would go to the ER just to be sure. Do you have any cramping? Have you done anything strenuous recently? Sex and straining can also cause spotting.
I had spotting in the second trimester with my second and third child and carried that both to full term.
