Answer:
Luteal phase.
Explanation:
Luteal phase occurs after ovulation (when the ovaries release an egg). To further justify this claim read the statements below:
The luteal phase of the menstrual cycle is the time between ovulation and your next period. It starts after ovulation, on day 15 of your cycle.
During the luteal phase, progesterone produced by the corpus luteum helps thicken the womb lining in preparation to receive a fertilized egg.
