I need someone's advice

So this is the first month off the nuvaring and I started taking my bbt and using OPK's. Now the "fun" part... I got a almost positive OPK on CD9 also with quite some EWCM (sorry for TMI) anyway I just don't get that massive drop on CD13... I had a lot, like a LOT of EWCM (TMI again, sorry) mixed with a little bit of blood since it was slightly pink/reddish. 
Stupid enough I didn't bring any more OPK's with me (I was away from home) so I couldn't test that day. Due to all the ewcm that day I would almost think I ovulated then... I did test again the day after but that line was just barely there.. so I never got a (near) positive OPK since CD9 ... what do you think, when did I ovulate and why the dip? Thanks in advance🤗
Ps. I'm not TTC.
