CM change question

Lindsey
So, I've had one miscarriage at 11 weeks back in December. My husband and I are trying again and I cannot remember my initial symptoms when I was first pregnant. I do remember things tasting different and being dog tired but that was pretty much it. I honk my boobs hurt too but I can't remember that now. Anyway my boobs have been hurting the past few day and I have had an increase in CM.  I don't test for another 4 days and I can't remember if a change in CM is an indicator or not...anyone know the answer to this question? I'm going to google it but I'm at work so I'll have to wait until I'm either at home or when my phone isn't inches away from dying. Thanks!!!!!!
