Patient's question:
Hello, I had my period on November 17th, and my cycle is about 35 days. I started tracking my basal body temperature on December 10th, and it has been consistently below 36.5°C. I'm using a mercury thermometer. Does this mean I didn't ovulate this month? And it's also unlikely for me to be pregnant.Doctor's answer:
Hello, based on your description, it is recommended that upon waking up, you should refrain from exercise and eating, and immediately measure your levels, fixed at 7 a.m., so that comparisons can be made. Sublingual measurement is less susceptible to interference from external environmental factors and is relatively stable.
