Ms. Li is an avid exerciser who regularly runs and cycles at the gym. Last week, after an intense spin class, she suddenly felt lower abdominal pain and visited Wuhan Central Hospital nearby. The doctor initially diagnosed her as pregnant.Ms. Li immediately protested: "Impossible! My periods have been perfectly regular these past few months—both timing and flow were identical to before. While I do experience abdominal pain, that's due to my chronic dysmenorrhea, so it's nothing unusual. Besides, my period just ended a few days ago—there's no way I could be pregnant now."
To confirm her pregnancy, the doctor administered a urine test, which returned positive, validating the initial suspicion.
The hospital's obstetrics and gynecology director explained that Ms. Li's pregnancy was an ectopic pregnancy with a low survival rate. Her previous menstrual cycles and dysmenorrhea were likely caused by abdominal pain resulting from abnormal vaginal bleeding after the ectopic pregnancy. However, due to the coincidental timing of her period and her accustomed perception of menstrual cramps, she failed to recognize this hidden pregnancy.
Doctors caution that women of childbearing age should heighten awareness of concealed pregnancies. Abdominal pain around menstruation and abnormal vaginal bleeding may signal such a condition. When experiencing these symptoms, individuals should promptly use pregnancy test strips for verification; severe cases require immediate hospital evaluation.
Can menstruation occur during pregnancy?
Is menstruation possible while pregnant?This question may sound absurd, yet it involves complex medical principles. After reaching maturity, a woman begins ovulating. During ovulation, the uterine lining thickens and forms a corpus luteum to prepare for implantation of a fertilized egg. If an egg encounters healthy sperm and becomes fertilized, the fertilized egg implants in the uterus. The corpus luteum then develops into the placenta that nurtures the fetus.
If menstruation occurs after pregnancy, it is likely vaginal bleeding caused by threatened miscarriage, ectopic pregnancy, cervical erosion, or similar conditions. It is best to seek prompt medical examination to identify the cause of the threatened miscarriage. For example, Ms. Li's "abdominal pregnancy" mentioned earlier was an ectopic pregnancy.
What causes menstruation after pregnancy?
What causes menstruation after pregnancy? Generally, menstruation ceases after conception, so why do some women still experience it?
1. Other causes of vaginal bleeding: Bleeding during pregnancy is also common with cervical polyps or erosion, and cervical cancer can cause vaginal bleeding.In extremely rare cases, menstrual-like bleeding during pregnancy may be interpreted as a physiological reaction following implantation of the fertilized egg.
2. Threatened miscarriage: If a woman has a history of missed periods, a positive urine pregnancy test confirms pregnancy. Should vaginal bleeding occur in this context, especially accompanied by lower back pain or abdominal discomfort, threatened miscarriage should be the primary consideration. The possibility of ectopic pregnancy must also be evaluated.
Bleeding during pregnancy is not true menstruation but indicates pathological changes in the uterus or its adnexa. Be particularly vigilant for ectopic pregnancy and threatened miscarriage, both of which are highly dangerous. If you experience bleeding after confirming pregnancy, seek immediate medical examination to determine the cause and receive timely treatment.
