Sooo confused!! Another ovulation question :)

I just had a CP that ended on 1/8. It began with very light spotting and mild cramps for the first 2 days. Beginning on 1/10 was when i would see the clot in the am but then the dark brown spotting on a pad and the occasional cramps. This continued until 1/21. That last day I was having major pains on my right side (maybe my ovary) into my hip. Also had a lot of CM the consistency of sticky glue but very stretchy. On 1/22 I took my first OPK and there was a line but not as dark as the control line. My DH and I bd'd that evening since I was finally not spotting. The CM continued until 1/24 in in mass quantities lol and we bd'd again that evening. Since that first OPK the line has become almost non existent. So now I'm wondering...did I O my last day of spotting?? Can that happen? And I'm not even sure if I should count the first 2 days since the spotting was barely there. For me that would be extremely early since i normally O on cd 19-20. I'm hoping that is the case and that the timing was good :)
