Introduction

In early pregnancy, elevated morning body temperature may be caused by non-disease factors such as increased progesterone levels and heightened metabolism, which generally do not require special treatment. It can also result from medical conditions like upper respiratory tract infections; if the temperature is too high, it can be managed through home care or medication. It is recommended to monitor body temperature during pregnancy and avoid wearing excessive clothing. If fever is severe due to infection, prompt medical attention is advised.

I. Non-disease Factors

1. Increased Progesterone Levels

During pregnancy, the corpus luteum gradually enlarges and continues to secrete progesterone, helping to maintain a stable environment for fetal development in the uterus. Elevated progesterone levels stimulate the body's thermoregulatory center, leading to a rise in body temperature. This is a normal physiological phenomenon and does not require specific intervention.

2. Increased Metabolism

After conception, the basal metabolic rate increases, which can raise body temperature by approximately 0.3 to 0.5°C above normal levels. It is recommended to drink plenty of water and consume a diet rich in calories, vitamins, and protein.

II. Disease Factors

Fever may also occur due to upper respiratory tract infections caused by exposure to cold. In such cases, it is important to drink ample warm water, eat light and easily digestible foods, and stay warm. If symptoms are severe, medication should be used cautiously under a doctor’s guidance; drugs such as amoxicillin may be prescribed.

It is advisable to monitor body temperature throughout pregnancy. Avoid wearing excessive clothing to prevent sweating caused by elevated hormone levels and metabolism, which could lead to catching a chill. If fever due to infection becomes severe, prompt medical attention is recommended.

Can an ectopic pregnancy be detected with a pregnancy test strip?

Ectopic pregnancy—commonly referred to as “tubal pregnancy”—typically cannot be detected using a home pregnancy test (urine dipstick test), which only indicates whether pregnancy has occurred. If you experience any discomfort or concerning symptoms, prompt medical evaluation is strongly advised. Detailed analysis follows: Once ectopic pregnancy is confirmed, strict adherence to the physician’s treatment plan is essential. During conservative management, patients must remain on bed rest and avoid activities that may trigger rupture of the ectopic mass—such as vigorous exercise, bending over, or straining during bowel movements.
