Is my period normal???

This is my thirde being on my period. My last two periods looked really normal. But today started mine again. So when I started today I had alot of blood. Then a couple hous later, there wa only a very very little amount of blood. Then about half an hur ago when I changed it, there was only very little blood. So does this mean it's endg already or what? Is this even normal??? Please help! Thanks!
