I started my period so I thought Tuesday night jan 1 and carried on til the next day jan 2. By the 3 expected day it had Completely stopped. Then came back spotting lighter Friday jan 4. By Friday evening it was gone again?. My periods are consistent and this has never happened to me. my bf seems to think i could be but i think its too soon to tell..could i be pregnant? I've had some signs and symptoms leading to believe its a possibility. Help.!
