Hello, the chances of pregnancy are low, but it is always best to take preventive measures beforehand.
Do not rely on the safe period.
If your period is more than a week late, it is advisable to see a gynecologist.

When it comes to delayed periods and elevated body temperature, there are several factors to consider, especially in the context of potential pregnancy. Your girlfriend's situation, where her ovulation occurred on November 18 and unprotected intercourse took place shortly after, followed by a delayed period, raises some important questions.

Firstly, it's essential to understand that a delayed period can be one of the early signs of pregnancy. After conception, hormonal changes occur in the body that can prevent menstruation. The hormone progesterone, which is produced after ovulation, helps maintain the uterine lining and can also lead to an increase in basal body temperature. If your girlfriend's body temperature has been consistently elevated, it could indicate that she is in the luteal phase of her cycle, which is typical after ovulation. However, if the temperature remains elevated beyond the expected time of menstruation, it may suggest pregnancy.

In your case, since her period was due on December 2 and is now two days late, it would be advisable for her to take a home pregnancy test. These tests are designed to detect the hormone human chorionic gonadotropin (hCG), which is produced shortly after a fertilized egg implants in the uterus. The best time to take a pregnancy test is after a missed period for the most accurate results. If she takes the test too early, it may not detect the hCG levels yet, leading to a false negative.

Regarding her fluctuating body temperature, it is not uncommon for women to experience temperature variations during their menstrual cycle. Some women report feeling hot or cold, which can be attributed to hormonal changes. If she is experiencing significant temperature fluctuations, it might be worth monitoring her temperature consistently to see if there is a pattern or if it remains elevated.

Additionally, other signs of early pregnancy can include breast tenderness, nausea, fatigue, and changes in appetite. However, these symptoms can also be related to premenstrual syndrome (PMS), which can complicate the interpretation of symptoms.

If the pregnancy test is negative and her period does not arrive, it would be prudent for her to consult a healthcare provider. There could be other reasons for a delayed period, such as stress, hormonal imbalances, or other health issues. A healthcare provider can conduct further evaluations, including blood tests or ultrasounds, to determine the underlying cause of the delayed menstruation.

In summary, while a delayed period and elevated body temperature can be signs of pregnancy, they are not definitive on their own. A home pregnancy test is the next logical step, and if the results are inconclusive or if her period does not arrive, seeking medical advice would be the best course of action. Monitoring her symptoms and maintaining open communication about any changes will also be beneficial as she navigates this situation.
