Question

A reader writes in asking if she is pregnant since she had her period on September 24th (Lunar August 27th) and did not have her period in October. If so, she wants to confirm whether her pregnancy month is the Lunar August or September. Since her last menstrual period was on Lunar August 27th, she wonders if she should ovulate in the Lunar September, making the pregnancy month potentially August or September. She is confused and hopes for a professional explanation.

Answer

A medical expert provided an analysis of the situation, indicating that if the reader indeed did not have her period in October, then her pregnancy month must be the Lunar September. The expert explains that based on the reader’s menstrual cycle, the ovulation period should be the following month, around October 10th Gregorian, which corresponds to the Lunar September. Therefore, if the reader became pregnant during this time, the pregnancy month should start from the Lunar September. However, the expert also mentions that although the duration of pregnancy is counted from the last menstrual period, if the reader became pregnant in the following month, the duration should be calculated from October 24th Gregorian.
