Menstruation after miscarriage


Hello Doctor: I underwent a Pap smear and HPV test in January of this year (since I have regular check-ups, many issues have been ruled out).
I have polycystic ovary syndrome.
My last menstrual period was from March 29 to April 5.
I took a pregnancy test on May 9, which showed two lines.
Then, on May 18, I suddenly experienced heavy bleeding.
On May 22, around 11 PM, while taking a shower, I passed a blood clot the size of my palm.
When I visited the doctor on May 23, they confirmed that I had a miscarriage.
The bleeding continued from May 18 until May 26, then stopped.
On May 31, I started having brown discharge (which only required a panty liner) until June 9, when I began to have menstrual flow.
During the day on June 11, I needed to use overnight pads, and as of now, June 16, the flow has decreased significantly, but it hasn't completely stopped.
There are some small blood clots.
I would like to ask the doctor, does June 9 count as my first menstrual period after the miscarriage? Is the amount and duration of bleeding I experienced considered normal?

Yumi., 20~29 year old female. Ask Date: 2023/06/16

After experiencing a miscarriage, many women have questions regarding their menstrual cycle and what to expect in the following weeks and months. It is important to understand that the body goes through significant hormonal and physical changes after a miscarriage, which can affect menstrual patterns.

In your case, it appears that you experienced a miscarriage on May 22, following a period of heavy bleeding that began on May 18. The bleeding you experienced after the miscarriage is often referred to as post-miscarriage bleeding, and it can vary significantly in duration and intensity from one individual to another. The presence of blood clots, especially small ones, is not uncommon during this time as the body expels the remaining tissue from the uterus.

The bleeding you noted starting on June 9 could indeed be considered your first menstrual period following the miscarriage. Typically, a woman's menstrual cycle can take some time to regulate after a miscarriage, and the first period may not resemble your usual cycles in terms of flow, duration, or symptoms. It is common for the first period to be heavier or lighter than normal, and it may also include clots, as your body is still adjusting to hormonal changes.

Regarding the duration and amount of bleeding you are experiencing, it is important to note that while some women may have a normal period that lasts 3 to 7 days, others may experience prolonged bleeding or irregularities in their cycle after a miscarriage. The fact that you have noted a decrease in bleeding intensity is a positive sign, indicating that your body is likely returning to its normal state. However, if you continue to experience heavy bleeding, large clots, or if the bleeding persists beyond a week or so, it is advisable to consult with your healthcare provider. They may want to perform an examination or an ultrasound to ensure that there are no retained products of conception or other complications.

In summary, the bleeding you experienced starting on June 9 may be considered your first menstrual period after the miscarriage, and the variations in flow and duration are generally normal. However, it is essential to monitor your symptoms and seek medical advice if you have any concerns about the bleeding or if it does not resolve as expected. Your healthcare provider can provide personalized guidance based on your medical history and current situation, ensuring that you receive the appropriate care and support during this time of recovery.
