Spotting?

Can spotting be heavy? Last night before I went to bed, I had cramping, not like my usual period cramps, just below my bellybutton. So I put a tampon in, this was like 1:30 in the morning. Fall back asleep and wake up again feeling like I had to puke, which I did, from the cramps, which now feel like normal cramps. Fell back asleep and went up to the bathroom around 10:30 , took my tampon out and it was barely covered, it was dark brown with a little bit of light pink. Normally when I start my period it’s usually a lot more blood especially the start of. Could this possibly be spotting? Or am I just getting my hopes up?
