Yes it is definitely possible. Alot of pregnancies have light spotting throughtout. As long as the blood is not bright red or dark in color everything should be fine. Unfortunately every feeling we have while pregnant makes us think something is wrong. Good luck =)
Spotting and cramps are common symptoms of pregnancy prior to a missed period. The spotting is not noticed by every woman but could be a sign of implantation. The cramps are usualy likened to period cramps.
