spotting?

Amanda

AF was meant to visit today, normally when I wake up on the day of my period she's there already like "hey girl, you ok? were gonna be emotional and angry today!" but she wasn't so I'm all like "is it my month now?" about 11:30 am I started spotting, I've never spotted before and I have heard this could be implantation bleeding. It is now 2pm and nothing since. when I was pregnant with my son I had a light period which made me think I was only 3 weeks pregnant when I found out but was actually near enough 8 weeks, so now I'm all confused, do I wait and see what's gonna happen? how long do you wait till you take a test when you're late? I'm so confused ahhhh
