I have been checking my cervix location, mucus and using a OPK. 2 days ago my cervix was low and had a white mucus that was fairly thin. OPK was negative. Yesterday is was still fairly low and mucus was the same, OPK negative. Today my cervix is high, feels open but the mucus is very white and very thick. OPK still negative. Do you think that I have already ovulated or am about to? Also, I just stopped using the Nuvaring and I dont know if that has influenced my cycle. Any help is much appreciated.
