Ok, so I've been checking my CM this month and I'm sorta new at this so I feel a bit confused. So, I've noticed the dry spell after my period but I didn't notice the sticky phase and now it seems creamy. How long does each phase last? I am supposed to ovulate next weekend I think so I don't know if something is wrong or if I will ovulate sooner than expected. How long does the creamy phase last usually? I also took a opk just to see and it was negative. Im on cd13 also.
