Q&A Index > Temperature drop in luteal phase
What does it mean if my temperature dips below the coverline during the luteal phase? Should I be worried? Could I be pregnant?
A single temperature point doesn't usually carry much significance on its own as individual temperatures can be affected by so many factors, both hormonal and non-hormonal. What you are looking for are trends and patterns over time.
If your temperature dips several times before your period is expected, then it could mean that you are not taking your temperature accurately (especially if you are not taking it at the same time) or that you did not really ovulate.
Fertility Friend will usually remove the ovulation detection and coverline when too many temperatures are in the lower range or missing. Ask for support if you are not able to interpret the pattern of your chart. Also, remember that the coverline carries no physiological meaning. It is just a visual tool.
