I would agree with Heather's comments. I used to typically have EWCM for a few days prior to ovulation. That is your most fertile time, so take advantage!! Before my cycles went from 28 to 25 days, I would usually have a positive OPK around day 11. Once they moved to 25 days, it changed to day 8 or 9. I usually had ovulation pain a day or two after my positive OPK. Good luck and SSBD to you!!
How long are your cycles normally? It's pretty common to have EWCM for a few days before ovulation, and ovulating on day 8 would have been very early. I've had cycles like that, too, though, where I would have lots of stretchy mucus early on and then by the time I ovulated (based on OPK and even sonograms), it felt like everything had dried back up again. I asked my RE about it once before I had an IUI (not that mucus matters when having an IUI, but I honestly thought I had already ovulated...I hadn't). He showed me with a mirror that there was in fact stretchy mucus up by the cervix where it counts. Maybe it's the same with you. Best of luck with everything!
