[/INST] Hello Kyoto;welcome to Chat Doctor To get pregnant you need to have the follicle mature 22-23 mm and rupture releasing the egg, and it happens on the 15th day in a regular menstrual cycle. As you had POD and irregular periods it may know only after follicular study, so please keep on doing it as you have started and in next 3-4 days the size of the follicle should reach the maturity and if it does not happen then you will need Chat Doctor injections in next cycle which your Gynecologist will decide based on your follicular study report. Thanks </s>
