My understanding is that when you're ovulating, your CM should be eggwhite in texture. If it was thick, it could mean you're getting closer to ovulating, or possibly already ovulated? I've taken the following from Fertility Friend - good article:

Sticky: Record your cervical fluid as "sticky" if it is glue-like, gummy, stiff or crumbly and if it breaks easily and quickly and if it is not easily stretched. It will probably be yellowish or white, but could also be cloudy/clear. You may or may not see some sticky cervical fluid before and after ovulation.
