Implantation?

Sharlea
Okay so I had this weird cramping. It lasted a good hour or so. I've had it before. When I got pregnant with my daughter. About a week later I started my so called "period" - it was light brown, then pink, then it was red for like 15 minutes, not enough for a tampon, barely enough for a pad it lasted 4 days. I took it as my period. Should I test??
