I feel pregnant. i had my period 11days early. not as heavy or painful. few days later had thick milky discharge with a pink hue. when should i test?

Take a test: Don't guess. Take a test. In today's world you do not need to wonder if you are pregnant or not based on symptoms. Pregnancy tests are available at any pharmacy and in minutes you have your answer. They can detect a pregnancy 7-10 days after conception. The best time is when you miss your period. If your symptoms were caused by pregnancy the the hormone would be high enough for detection.
