Need some help? Anyone TTC?

Have just posted but think my question wasn't clear enough so am re-doing it. I have very irregular cycles and therefore am concerned I don't ovulate every cycle. However I have been charting my basal body temp for a few months and am getting a regular 0.5 - 0.7 increase in my temp that coincide with the changes in my cervical mucus. As far as I'm aware I wouldn't get the temp increases unless I'm actually ovulating as its the progesterone released that causes the rise. Is this true? Do you think I am actually ovulating despite the irregular cycles?
