If you have a 22-25 day cycle, your ovulation would fall on the 8th- 11th day of the cycle unless you have a short luteal phase. The ovum at rupture is usually 18mm. Anything beyond that size is not ideal for rupture as cyst
is formed. As such, you may not have ovulated this cycle.To predict ovulation you have to use ovulation kits or fertility
monitors. Ovulation occurs within 30 hours after peak LH levels are attained.Please contact your gynecologist for further details Take care.
