implantation?

Caitlyn
So the last week I've been feeling off and haveing loads of pregnancy symptoms. Even my husband thinks I'm pregnant... tonight (morning for me because I work nights) when I went to the bathroom when I wiped there was very light pink blood/cm mixture on the tp. And am now having mild cramping. My period is due in two days. I'm just curious if it could be implantation bleeding since it's so light? Any input would be helpful! Thanks!!
