how light is it? is it a regular flow just lighter than normal or is it spotty?
if you had sex yes it is possible that you're pregnant you need to wait at least 2 weeks before taking an hpt.
Pinky, I don't know how you know about implantation bleeding, yet you're posting the question that you did in the pregnancy 18-34 forum. you are blowing my mind.
may be implantation bleeding. the timing seems right.
take a pregnancy test in a week, it should give you an accurate result
yes you could be pregnant. take an hpt. if it turns out you are not pregnant i HIGHLY suggest using condoms AND getting on some form of b/c.
