Pinkish/clear discharge

I'm 5 days late on my period and I've been having small cramps for about 4 days. Yesterday I just spotted like one time and today I have a few times and it's pinkish colored sometimes clear. I usually start very heavy but this time is unlike any other. Its only when I go to wipe. I have had none on the pad im wearing. Can anyone tell me what might be going on?
