BBT Charting
Understand your basal body temperature chart and what it reveals about your cycle.
Viewing Your Chart
You can view by cycle or across multiple cycles to see patterns.
Understanding the Chart
Temperature Scale
The Y-axis shows temperature in your preferred unit (°C or °F). The range is typically narrow (about 1°F or 0.5°C) to show subtle changes.
The Coverline
Lova draws a horizontal coverline on your chart:
Temperature Shift
After ovulation, you should see:
A rise of 0.2°C (0.4°F) or more
Sustained for at least 3 days
Temps staying above the coverline
3-Day Confirmation
Lova confirms ovulation when 3 consecutive temperatures are above the coverline. This is the standard fertility awareness method.
Chart Patterns
Biphasic (Normal)
Two distinct phases: lower temps before ovulation, higher after
Monophasic
Flat temps without clear shift - may indicate anovulatory cycle
Slow Rise
Gradual temperature climb over several days - normal variation
Fallback Rise
Rises, dips briefly, rises again - initial rise still indicates ovulation
Chart Markers
Lova marks special events on your chart:
Adjusting Temperatures
If you took your temperature at an unusual time:
Tap the data point on the chart
Add a note about the time difference
Mark as "unreliable" if needed
Time Adjustment
Some fertility awareness methods suggest adjusting temps by 0.1°F per 30 minutes if taken early/late. Lova can show both raw and adjusted values.
Compare Multiple Cycles
This helps identify your typical ovulation timing.
