Spotty EWCM. Tmi

I'm on cd 16, and my first round of clomid. I took clomid 50mg for days 5-9. I have been doing opks since cd 12, and nothing. Other than on cd 13 there was a faint line, almost as dark as the control line, but I know this still means no surge. I haven't had another line since then. Today I had a little pink blood to my EWCM a couple times when I wiped from using the bathroom. Anyone know why or if this is possibly ovulation? Should we bd anyway? I'm so confused. Any help would be wonderful at this point.
