I would go by the date you have which seems to be 33 days. Its better to expect it later in the month and get it early than to expect it sooner and get your hopes up for nothing.

For someone with a somewhat irregular cycle like you, your best bet it going to be to use ovulation predictors, cervical mucus tracking, bbt, or some combination of those three. Your ovulation day determines your cycle length, so when you have cycles of different lengths it means you're ovulating on different days (so you might ovulate on cd 14 one month and have a 28 day cycle, then ovulate on cd 18 and have a 32 day cycle). So you're not going to be able to accurately predict your ovulation date from past cycles, it will change from cycle to cycle. Opk's and cm tracking let you know when you're about to ovulate, and bbt charting confirms that ovulation has occurred - you can mix and match them to best suit your needs and preferences.

All of that assumes that you'd feel more comfortable having a way to actively track and control the process. It's equally valid to take a more laid-back approach, and if that's your preference your best bet it just to plan to have intercourse every other day from cd 10-cd 22 (that will cover your fertile window for a shorter-than-normal cycle up to your longest cycle). Good luck to you!
