My boneless chicken expires today and it has a couple of tiny blood spots. Is it safe to cook?

I bought some boneless chicken some time ago that expires April 30th (today). I stuck it in the freezer, but removed it from the freezer yesterday and put it in the fridge so it could thaw in time for cooking today. While cutting it up I noticed that it had a couple of tiny spots of blood in it, and also the sheet on which the chicken was placed in the packaging was stained red, something I don't normally see. Is the chicken safe to cook and eat? It doesn't smell bad.
