Flat BBT Readings
Why am I getting "flat" basal body temperatures?
If your BBT seems to be around the same level all the time, the culprit is usually your thermometer. Even when you are taking your temperature at the same time and following all the guidelines, there is usually some fluctuation in temperatures. Your first step is to check your thermometer's battery or get a new thermometer. If your basal body temperatures are still flat, and/or show no sign of a biphasic (ovulatory) pattern when you would expect them to, this is something to ask your doctor about if it happens for a few cycles.
