Postpartum menstruation


Hello, doctor.
It has been over eight months since I gave birth, and I only had my period in the third month postpartum.
Since then, I haven't had any menstrual cycles, and I am worried about the possibility of being pregnant.
I have taken three pregnancy tests, all of which were negative.
I am unsure what the reason could be and whether it is related to my ongoing breastfeeding.
However, it has been quite a while, and I can't find anyone in a similar situation to ask.
Is this normal? Should I see a doctor?

ya, 30~39 year old female. Ask Date: 2004/06/28

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello: In women who are breastfeeding, the levels of prolactin can be elevated, which may suppress ovarian function and ovulation.
Therefore, it is understandable that menstruation may not occur due to the lack of ovulation.
It is advisable to visit a hospital for a blood test to rule out other possible causes, which may include insufficient sleep, being underweight or overweight, intrauterine adhesions, chronic inflammation, hormonal imbalances, and so on.
It is recommended to schedule a time for further examination and treatment at the hospital.
Sincerely, Dr.
Lu Li-Cheng, Department of Obstetrics and Gynecology, Taoyuan Hospital, Ministry of Health and Welfare.

Postpartum menstruation can be a complex topic, especially for new mothers who are navigating the changes in their bodies after childbirth. It is not uncommon for women to experience delays in the return of their menstrual cycles, particularly if they are breastfeeding.
After giving birth, many women find that their menstrual cycles do not return immediately. This delay can be influenced by several factors, including hormonal changes, breastfeeding practices, and individual variations in recovery. In general, breastfeeding can suppress ovulation due to the high levels of prolactin, a hormone that promotes milk production. This suppression can lead to a condition known as lactational amenorrhea, where menstruation is absent for an extended period.
In your case, since you mentioned that you have not had a menstrual period since the third month postpartum and are still breastfeeding, this could very well be a normal response of your body to the hormonal environment created by breastfeeding. Many women experience a delay in the return of their menstrual cycles for several months or even longer while exclusively breastfeeding.
However, it is important to note that while breastfeeding can delay the return of menstruation, it is not a foolproof method of contraception. If you are concerned about the possibility of pregnancy, it is good that you have taken pregnancy tests, which have come back negative. If you continue to have concerns about pregnancy or if you experience any unusual symptoms, it would be wise to consult with a healthcare provider.
Additionally, if you are experiencing any other symptoms such as significant weight changes, excessive fatigue, or any other health concerns, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, including a physical examination and possibly blood tests, to assess your hormonal levels and overall health.
In summary, it is quite normal for menstruation to be delayed postpartum, especially in the context of breastfeeding. However, if you have ongoing concerns or if your situation changes, do not hesitate to reach out to a healthcare professional for personalized advice and support. Your health and peace of mind are important, and a medical professional can provide the reassurance and guidance you need during this time.
