What "counts" as a period?

Can I still say I missed my period if I had bleeding? It only lasted like two hours a day for two days, and most of it was brown..some red. 
The rest  of the time and the third day was either nothing or pink spotting/brown discharge afterwards. My normal periods are constant red blood and pretty medium flow. So it's definitely not normal for me, but does it count as a missed period idk
