If you do not ovulate because of abnormal periods does taking oral contraceptive help you ovulate if you miss a pill around the time you are supposed to ovulate?

Taking oral contraceptives helps keep you regular so your periods are on time every month. I can't say it helps you ovulate because you don't ovulate while on the pill. If you miss a pill during the time you would have normally ovulated without the pill, take it as soon as you remember and use another form of birth cotrol as a backup.

No, the combination pill doesn't work like that.

The combination pill suppresses your entire menstrual cycles to stop ovulation, if you skip a pill around the time you think you should have ovulated you won't ovulate, it simply doesn't work like that - if anything this will cause even greater irregularity. If you have abnormal cycles there is a reason for that so see your doctor to investigate what is wrong and look into treatment options.

Hormonal birth control does NOT regulate periods - this is a myth.

Hormonal birth control suppresses menstrual cycles in order to stop ovulation, as you no longer ovulate you also no longer menstruate - the bleeding women experience is a withdrawal bleed caused by the drop in synthetic hormones when going from active to inactive pills. If a woman has irregular cycles that should be investigated and treated, not covered-up with the pill at risk to health.
