confused

Samantha
Please can someone help me with this as it's my first time charting and I'm finding it really confusing. I know I haven't started straight away as I only got it delivered mid cycle but I feel that the rise must be significant somehow.
I have been using opks too but have not had a positive reading although I did only start them on the 12th and there seems to have been a faint line which has just become more faint as the days have passed.  
I have not had ewcm although it has been really heavy as though I have peed myself and a little creamy too but more wet than anything (sorry if tmi) I've also had cramps since cd12 on my left side which are still there although I get them every month around o time.
I am thinking that I have either missed o or that it just ain't going to come this month but would be interested in what others made of this.
