High fertility
Medium fertility
Phase 1
Menstruation
Days 1โ€“5
The uterine lining sheds. Estrogen and progesterone are at their lowest. Energy may be low โ€” rest is important.
Phase 2
Follicular Phase
Days 6โ€“13
Estrogen rises as follicles develop in the ovaries. Energy increases, mood improves. Fertile window begins toward the end.
Phase 3
Ovulation
Day 14 (avg)
A mature egg is released from the ovary. LH surges. This is peak fertility โ€” the egg lives 12โ€“24 hours. Sperm can survive 3โ€“5 days.
Phase 4
Luteal Phase
Days 15โ€“28
Progesterone rises, preparing the uterus for implantation. If no fertilization, hormone levels drop and the cycle restarts.
๐Ÿงฌ Understanding Ovulation Signs
๐Ÿ’ง Cervical Mucus
Becomes clear, stretchy, and egg-white-like near ovulation โ€” your most reliable physical sign.
๐ŸŒก BBT Rise
Basal body temperature rises 0.2โ€“0.5ยฐC after ovulation and stays elevated until your next period.
๐Ÿฉธ Mittelschmerz
Some women feel a twinge of pain on one side of the abdomen โ€” this is ovulation cramps.
๐Ÿ“ˆ LH Surge
OPK strips detect the LH hormone spike that triggers ovulation 24โ€“36 hours later.

๐Ÿ’ก Tip: Measure BBT immediately after waking, before getting up. Use a BBT thermometer for accuracy to 2 decimal places.
