Period help??

I'm having all the usual signs of being on my period such as cramps and bleeding, but I'm used to heavy bleeding. The first day on my period it was spotty and pink. Second day it picked up a little bit more (not by much) and it's still pink. Today so far it's still very light and normally by the 2nd or third day it's pretty heavy with blood clots and all, but it's not though the cramping is just as bad as usual. Do you guys think it's my period but just being weird or do you think it could be something else and if so what?

What the blood looking like fyi
