Is this early pregnacy symptom? Should I test ?

Mandeep

My af was supposed to come on Dec 13 but hasn’t shown up yet. I did have blood clots medium size one per day for 2 days and no bleeding or anything. I am also getting lot of thick egg white clear cervical mucus which I have never had before. Otherwise No symptoms of pregnancy. Can you please advise if I should take a test? If yes, what time of the day should I test to get more accurate results?
