AF due 04/11.

Last period was 03/12, lasted through the 15th. Actively ttc, stable relationship, renting a house, etc.. 
Yesterday morning, I woke up to some brown sticky, stretchy CM. (Spotting?) later last night it turned to a creamy brown CM. woke up this morning, expecting an early AF, but got more brownish pink CM, but kind of watery. I'm so confused on whether or not to test.
