I finished pumping and my milk is pink. Should I throw it away?

Besides blood that will cause your milk to be pinkish, another potential cause is if you had consumed food that are naturally red/pink or food with red dyes. For example, beets or any red fruit drinks may cause your milk to be coloured. Regardless, both will not be harmful to your baby and could still be consumed. If you are worried, call up your doctor for some clarifications. Hope this helps!
