Cervical mucus is definitely a good way to tell if you are ovulating, but it really needs to be used in conjunction with another method becuase you can have several patches of CM throughout your cycle. Kellie84 -- great job with already charting your periods. You really should consider charting your waking temperature (BBT) as well. That really is the best way to confirm that you are ovulating. Ovulation predictor kits also work well.
Ovulation is typically thought of as ocurring 14 days before the start of the next cycle, not 14 days after the start. This very well could be a fertile time for you because this is 14 days before cycle day 36. I hope this makes sense. If it doesn't, let me know and I will describe it another way.
