Ewcm cd 20?! What would you do??? Semen analysis wed!!!

Ok I started metformin little over a month ago. (Very mild pcos is what my doc is thinking). I don’t use opks anymore since my mc in aug. I have usually a pretty normal period. Every 27-29 days. I am not sure when I ovulated. But I am having tons of ewcm today on cd 20. Could I Ovulate his late? Pregnant? I just got my first ever basal thermometer delivered 3 days ago but I’m also sick with an ear infection, so not sure how reliable those 3 temps are or was not able to temp any other time to compare it to. BUT my husband has an appt this wed for a semen analysis and has to abstain from sex until then. My question is.Do we bd anyway and reschedule if I am ovulating late? I don’t know what to do!
