Will Ovarian Cysts Affect My Menstrual Flow?

Will continuous bleeding from a cyst cause menstruation to become very light?

At the end of May, I experienced diarrhea accompanied by sudden bleeding, although my menstrual period had just ended.
I went to see a gynecologist, who diagnosed me with a cyst on my right side.
I have been undergoing medication treatment, and last week I had a follow-up ultrasound, which showed that the cyst has decreased in size.
Now, I am waiting for my next menstrual period, but I suddenly recalled that during my last visit, I mentioned that my menstrual flow was lighter than usual.
The doctor explained that this was due to the cyst causing ongoing bleeding, which resulted in a reduced menstrual flow.
This time, I am experiencing more bleeding than last time, although it is still not the amount typical for a menstrual period—just slight spotting.
I am concerned whether this could affect the arrival of my menstrual period.
Currently, I am experiencing mild pain on both sides and some bleeding, but it is not enough to be considered a menstrual flow, just some small blood spots.
Should I continue to wait, or do I need to see a gynecologist again?

Please consult with an obstetrician-gynecologist for an examination and discuss it in person.
The situation you described does not necessarily indicate a problem, but it should not be ignored either.
Only after the examination can the physician gain a better understanding.

Ovarian cysts can indeed affect menstrual flow, and your situation raises several important points regarding the relationship between ovarian cysts, menstrual cycles, and potential bleeding.
Firstly, it’s essential to understand what ovarian cysts are. Ovarian cysts are fluid-filled sacs that can develop on the ovaries. They are quite common and often form during the menstrual cycle. Most cysts are benign and may resolve on their own without treatment. However, certain types of cysts, such as functional cysts (which include follicular and corpus luteum cysts), can influence hormonal balance and menstrual flow.

In your case, the bleeding you experienced after a bout of diarrhea could be related to the ovarian cyst. If your doctor indicated that the cyst was causing bleeding, it is possible that this bleeding could interfere with your menstrual cycle. Cysts can sometimes lead to irregular bleeding or changes in menstrual flow, including lighter or heavier periods. This is because the hormones produced by the cyst can affect the endometrial lining of the uterus, which is what sheds during menstruation.

You mentioned that you have been experiencing some pain on both sides and have noticed some light bleeding or spotting. This could be a sign that the cyst is still present and may be causing some irritation or hormonal fluctuations. It’s also worth noting that if the cyst is large or if it ruptures, it can lead to more significant pain and bleeding, which may require medical attention.

Regarding your concern about whether you should wait to see if your menstrual period arrives or if you should consult a gynecologist again, it’s generally advisable to seek medical advice if you experience any unusual symptoms, especially if you have persistent pain or abnormal bleeding. While it’s possible that your menstrual cycle may normalize as the cyst resolves, any significant changes in your cycle or ongoing discomfort warrant a follow-up with your healthcare provider. They may recommend further imaging studies, such as an ultrasound, to monitor the cyst and assess any changes in your ovaries or uterus.

In summary, ovarian cysts can affect menstrual flow and may lead to irregular bleeding. Given your symptoms of pain and light bleeding, it would be prudent to consult your gynecologist for a thorough evaluation. They can provide you with personalized advice and treatment options based on your specific situation. Remember, it’s always better to err on the side of caution when it comes to your reproductive health.
