Hi!
With irregular periods it can be difficult to know exactly when to test.  Most pregnancy tests become positive about 14 days after ovulation.  If it has been longer than 28 days since your last period, then it would be quite reasonable to test.  I usually then recommend testing once per week until the test is positive or the period starts.
If you are NOT trying to conceive, oral contraceptives can be quite nice since they regulate your period too!
Good luck!
