What are the possible reactions of having sex during early pregnancy?
I just became pregnant not long ago, and my partner and I couldn't help but have sexual intercourse. Afterward, I have been feeling very anxious, worrying about the impact on the fetus. I would like to ask, what are the typical reactions or effects of having sex during early pregnancy?

Having sex during early pregnancy may cause reactions such as bleeding, abdominal discomfort, and vaginal infections.
During early pregnancy, the first 12 weeks of gestation, the embryo is in a critical stage of development. Sexual intercourse might lead to mild vaginal bleeding, usually due to the cervix becoming more sensitive and congested during pregnancy. This is generally not serious, but consulting a physician is still recommended.
Some pregnant women may experience abdominal discomfort or pain, which could be due to uterine expansion or muscle tension caused by sexual activity. If the pain persists or worsens, immediate medical attention is advised. Unprotected or unhygienic sex may allow bacteria to enter the vagina, leading to gynecological infections such as vaginitis, which can negatively affect both the mother's health and fetal development.
To ensure the health and safety of both mother and baby, it is recommended to avoid sexual intercourse during pregnancy, especially during the first and third trimesters. Pregnant women should get adequate rest, avoid excessive fatigue, maintain healthy lifestyle habits, and attend regular prenatal checkups to ensure maternal and fetal well-being. If any discomfort occurs, prompt medical consultation is advised.
