Introduction

Under normal circumstances, sexual intercourse is not recommended at 39 weeks of pregnancy, as it may cause adverse effects. At 39 weeks, pregnancy has reached the late stage, and the woman's uterus becomes more sensitive. During sexual activity, the uterus may be stimulated, leading to contractions. Additionally, prostaglandins in male semen may also induce uterine contractions. Strong contractions can result in preterm labor.

In general, sexual intercourse is not recommended at 39 weeks of pregnancy, as it may cause adverse effects. The specific reasons are as follows:

At 39 weeks of pregnancy, women are in their third trimester. At this stage, the uterus becomes more sensitive, and sexual activity may stimulate the uterus, leading to contractions, which can negatively affect the health of both the mother and the fetus. Moreover, prostaglandins present in male semen may also trigger uterine contractions. Strong contractions may lead to preterm labor, and preterm infants may still have some underdeveloped organ systems, which could seriously impact the newborn's health.

In addition, during the later stages of pregnancy, the physical burden on the pregnant woman is already significant, and the enlarged abdomen can make movement inconvenient. Sexual intercourse may cause further fatigue and discomfort, worsening symptoms such as shortness of breath, back pain, and腰酸背痛 (soreness and pain in the waist and back).

In daily life, to ensure the health and safety of both the pregnant woman and the fetus, sexual activity should be avoided as much as possible during the third trimester to prevent any negative consequences.

Can you get braces while pregnant?

In general, it is possible to wear braces during pregnancy, but the sensitive periods of the first and third trimesters should be avoided, with the second trimester being the preferred time to begin orthodontic treatment. Pregnancy itself does not affect the effectiveness of orthodontic correction; however, there are special physiological changes during pregnancy. The first trimester is a critical period for fetal organ development, and pregnant women often experience nausea, vomiting, and other early pregnancy symptoms. Wearing braces at this stage may exacerbate oral discomfort.

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

In general, ectopic pregnancy can be detected as pregnancy using a urine pregnancy test strip; however, the test strip cannot distinguish whether the pregnancy is ectopic. If the pregnancy test is positive, especially when accompanied by symptoms such as abdominal pain and vaginal bleeding, prompt medical evaluation is necessary. An ultrasound and blood beta-hCG (human chorionic gonadotropin) test should be performed to confirm the location of the pregnancy and prevent potential health risks.

Can hepatitis B women with high viral replication first reduce viral load before pregnancy?

In general, women with high levels of hepatitis B viral replication are advised to reduce their viral load before pregnancy, as this can significantly lower the risk of mother-to-child transmission and protect the health of both mother and baby. If a woman with high hepatitis B viral replication becomes pregnant directly, the virus may remain highly active during pregnancy, increasing the likelihood of fetal infection through the placenta, as well as raising the risk of complications for the mother such as abnormal liver function and hepatitis during pregnancy.
