Am i pregnant??

Okay, so my AF is 4 days late and i am getting these mild cramps here and there. There is some nausea, and i have been feeling really tired. When AF was 2 days late i took a test i got a neg result, i took another test the next day and still neg. My CM is cottage cheese like (tmi) sorry and there is more of it. Should i wait a little longer to test?
