How does my BBT change during my cycles?Updated 6 months ago
Changes in your BBT correlate with changes in your menstrual cycle. Before ovulation, your BBT ranges from 97°F (36.1°C) and 97.5°F (36.4°C). After the egg releases during ovulation, your BBT increases between 97.6°F (36.4°C) and 98.6°F (37°C).
