Spotting ??

I've had all these different signs of pregnancy and I kinda have this slight feeling that I am but I'm not sure, anyway last night I had to pee and noticed when I whipped I've been spotting my period isn't due at all yet! And I did have a bleed for my last period but had no clots at all (odd) and it was lighter, am I pregnant? I never get spotting between my menstural never!! It's the tiniest amount as well!
