would it be too early to test...

this Sunday the 5th? It will be 2 wks past possible conception and 12 days past possible ovulation. and 4 days before expected period. (Im new to all this). The past 5 days in a row I've had mild sore breasts and the past 8 days (tmi) increase in milky creamy cm. I don't want to test too early. I've read so much online. some say they didnt get a positive til 3 days past missed period and some had a positive 5 days before missed period! thanks everyone for ur input and thoughts!
