Answer:
Ovulation usually happens 12 to 16 days before the menstrual period begins.
Step-by-step explanation:
Ovulation is nothing more than the process of the release of an egg by the woman's body. This is a process that occurs with each menstrual cycle through hormonal changes proper to the female body. The woman's body raises luteinizing hormone (LH) to stimulate the ovary to release an egg from its reserve. Thus, ovulation usually occurs 24 to 48 hours after this hormone increases. In addition, ovulation usually occurs 12 to 16 days before the start of the next menstrual period.
