Analyze Basal Body Temperature (BBT) shift for ovulation tracking
Clinical Tracking Rule: Following ovulation, progesterone causes basal body temperature to rise by approximately $0.2^\circ\text{C} \text{ to } 0.5^\circ\text{C}$ ($0.4^\circ\text{F} \text{ to } 1.0^\circ\text{F}$). Enter your baseline follicular temperature and current resting temperature below.
