Menstrual flow has decreased?


I would like to ask about my menstrual cycle.
It has been 1-2 days since my period started, but the flow is significantly lighter than before (almost half).
I had a surgical abortion last year, but my periods have been normal since then.
I had sexual intercourse with my boyfriend in January, but he used a condom and withdrew before ejaculation.
My period started around February 2nd or 3rd and lasted about 6-7 days (I usually have a 7-day cycle).
However, the day before my last period started, I felt a strong urge to urinate every 1-2 hours, but only a small amount would come out, which was strange.

This time, my period was delayed a bit and started on March 14th or 15th, but the flow is very light, and I only need to change a pad once or twice a day.
The blood is dark, not bright red, which is unusual for me.
I am concerned about whether I might be pregnant or if there are other reasons for my lighter period.
Additionally, the frequent urge to urinate—could it be due to an infection or another cause? I am currently abroad, so it's not convenient for me to see a doctor.
I would appreciate your advice as soon as possible because I am feeling very anxious about this situation, as I have never experienced anything like this in the past two to three months.
Thank you.

Hello: 1.
Please come in for a pregnancy test.
2.
There are many reasons for light menstrual flow; a check-up is necessary to determine the cause, but the most common reason is irregular menstruation.
3.
Frequent urination may indicate a urinary tract infection; a urine test is needed to confirm.

Understanding changes in menstrual flow can be quite concerning, especially when accompanied by other symptoms. Based on your description, there are several factors to consider regarding your menstrual changes and urinary symptoms.

Firstly, it’s important to note that menstrual flow can vary significantly from month to month due to a variety of reasons. Stress, hormonal fluctuations, changes in diet or exercise, and even illness can all impact your menstrual cycle. Since you mentioned having a history of artificial abortion, it’s possible that your body is still adjusting to hormonal changes, even if your periods have been regular since then.
The fact that your menstrual flow is lighter than usual and appears darker could indicate several things. Darker menstrual blood can be a sign that the blood has taken longer to exit the uterus, which is not uncommon, especially if the flow is lighter. This can happen due to hormonal imbalances or changes in the uterine lining. It’s also worth noting that lighter periods can sometimes be a result of pregnancy, but given that you used protection and practiced withdrawal, the likelihood of pregnancy is lower. However, no contraceptive method is 100% effective, so if you have concerns about potential pregnancy, a home pregnancy test could provide clarity.

Regarding your urinary symptoms, the frequent urge to urinate, especially if you are only passing small amounts, could suggest a urinary tract infection (UTI) or another bladder issue. UTIs are common and can occur even in the absence of sexual activity. Symptoms can include increased frequency of urination, urgency, and sometimes discomfort during urination. If you suspect a UTI, it’s advisable to seek medical attention, as untreated infections can lead to more serious complications.

Additionally, hormonal changes can also affect the bladder and urinary tract. For instance, fluctuations in estrogen levels can influence urinary function and may lead to increased frequency of urination or changes in urinary habits.
Given that you are currently abroad and may have limited access to healthcare, it’s essential to monitor your symptoms closely. If your menstrual flow does not return to normal in the next cycle, or if you experience any additional symptoms such as fever, severe pain, or persistent urinary issues, it would be prudent to seek medical care as soon as possible.

In summary, while your symptoms could be attributed to a variety of factors including hormonal changes, potential pregnancy, or a urinary tract infection, it’s crucial to keep track of your menstrual cycle and any accompanying symptoms. If you have the opportunity, consider taking a pregnancy test and, if necessary, consult a healthcare provider for further evaluation. Your health and peace of mind are important, and addressing these concerns promptly can help alleviate anxiety and ensure your well-being.
