At six o'clock in the morning on the twentieth, Ruby Gregory was woken up by the alarm clock. She drowsily raised her hand to turn off the alarm, then reached out from the pillow, grabbed the thermometer and placed it under her armpit.
About five minutes later, Ruby took out the thermometer, opened her eyes, and looked at it. Then she suddenly sat up in bed, looked carefully again, picked up her phone to record the body temperature curve. She found that her body temperature was 0.6 degrees Celsius lower than yesterday.
To be on the safe side, Ruby shook the thermometer and placed it under her armpit again. Another five minutes later, she took it out, and it was still 0.6 degrees Celsius lower than normal body temperature.
As she held the thermometer, Ruby suddenly became tense.
Tonight, tonight, she must have sex with Steve Burton because tonight, her pregnancy rate would be at its highest.
But how could she have sex with Steve tonight?
