Understanding Your Cycle
Follicular Phase (Days 1-14)
The first half of your cycle begins with your period. After your period ends, your body prepares for ovulation by developing follicles in your ovaries.
Ovulation (Around Day 14)
Ovulation typically occurs mid-cycle when an egg is released from your ovary. This is your most fertile time.
Luteal Phase (Days 15-28)
After ovulation, the follicle transforms into a corpus luteum, which produces progesterone to prepare the uterus for a potential pregnancy.
Common Symptoms by Phase
This calculator provides estimates based on average cycle information. Actual ovulation can vary due to many factors including stress, illness, travel, or hormonal fluctuations. For medical advice, conception assistance, or contraception, please consult with a healthcare provider.
