positive sign or not?

Recently I've been checking my cervixat least  once a day for the past couple of months. It's usually either : very high so I can't reach it, or very low and soft and open. However today I've just had a massive (sorry TMI) glob of EWCM .. so I checked my cervix to see if it was open but it is so closed it doesn't even feel like there is an opening there!! It's NEVER felt closed to me either!! And what was the EWCM about? Had ovulation pains last week????
Hope this makes sense and someone can shed some light!
