Please could someone have a look and see what they think?

so last saturday i had EWCM (or so i thought) and then on monday morning my DH and i BD, monday afternoon i had a positive OPK so early tuesday morning (1am) we BD again, then tuesday night, then no BD wednesday, Thursday (don't know about tonight depends what time he gets home from work) i went to the toilet today and i have EWCM again so dose this mean that the OPK was wrong and i'm now ovulating now? thanks
