I have pinkish losses (I am not in my menstrual period) and these losses smell like iron. What should I do?

It is likely that the pinkish discharge with a metallic smell that you are experiencing is spotting, which is slight bleeding outside of your regular menstrual cycle. This could be due to a change in your birth control pill. In this situation, it is best to continue taking your pill as prescribed and the bleeding should stop on its own.
