Some scientific evidence on “signs of unsuccessful conception”

Here is some scientific evidence on “signs of unsuccessful conception”:

1. Reference: “Normal menstrual cycle and menstrual disorders” from the National Institute of Child Health & Human Development (NICHD) ( Regular menstrual cycles are a strong sign of successful ovulation and the possibility of pregnancy. When women have regular menstrual cycles, it indicates that the uterine lining has been prepared for the implantation of a fertilized egg. Conversely, irregular menstrual cycles may disrupt the ovulation pattern, reducing the chances of successful conception.

2. Reference: “Urinary pregnancy test: Evaluation of current and future technologies” published in the Journal of Clinical Investigation ( Urinary pregnancy tests detect the presence of human chorionic gonadotropin (hCG) hormone, a hormone produced by the developing placenta during pregnancy. Home pregnancy tests, when used correctly, can provide accurate results within a week after a missed period. A negative pregnancy test result after a missed period indicates that conception has not occurred.

3. Reference: “Early pregnancy symptoms and signs” from the Mayo Clinic ( While not all women experience early pregnancy symptoms, some common signs include nausea (morning sickness), breast tenderness, fatigue, and frequent urination. The presence or absence of these symptoms may provide clues to the likelihood of pregnancy. However, it is important to note that these symptoms can also be caused by other factors, such as premenstrual syndrome or stress.

4. Reference: “Bleeding in early pregnancy” from the American College of Obstetricians and Gynecologists (ACOG) ( Light bleeding or spotting immediately after ovulation, called implantation bleeding, can sometimes occur when the fertilized egg implants into the uterine lining. However, heavier bleeding or passing clots may indicate early miscarriage.

Early recognition of signs of unsuccessful conception plays an important role when you are trying to conceive. Actively seek reliable information and consult with a fertility specialist is the right step to get appropriate support/treatment, helping to make the dream of a complete family a reality soon.
