You can have EWCM for 5 or 6 days before you ovulate. It means you are probably fertile but doesn't necessarily mean you are ovulating. I notice your previous cycle seems to have been annovulatory - are you just coming off BCP or Depo? Because that can really mess up your cycles.

I would keep BDing until you are sure you have ovulated. Sometimes you may have several patches of EWCM in your cycle, especially leading up to ovulation.

Also, don't give up on the OPKs - what time of day are you doing them? I have found the best time of the day is 1pm, and make sure you don't drink any water/empty your bladder for at least 2 hours (pref 3) beforehand. Some don't ever see technical positives, but take the darkest they see as a positive.
