Pregnancy Test Negative but Irregular Periods: What Should You Do?

A single line on a pregnancy test indicates a negative result, but if your menstrual cycle is irregular, it could be due to various factors. It's important to consult a healthcare professional to determine whether you are pregnant or if there may be an underlying health issue affecting your menstrual cycle?

Before February of this year (including February), my menstrual cycle was normal and regular.
I did not experience any irregularities.
This year, I missed my period for 45 months, then had it on June 22, but missed it again in July.
A few days before my period in June and at the beginning of August, I took pregnancy tests, both showing a single line, using morning urine and following the instructions carefully.
Between February and June, I had sexual intercourse approximately three times, always using condoms.
After June, I did not have any sexual activity, but I feel like my abdomen has become larger, although I am unsure if it is due to weight gain or pregnancy.
I previously weighed 55 kg and now weigh around 57.5 kg.
Given this situation, could I be pregnant? If not, should I seek medical attention?

Hello, the factors that can affect the menstrual cycle or cause intermenstrual bleeding are numerous, including age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraceptive pills, diet, polycystic ovary syndrome, uterine or cervical lesions, infections, ovulation, pregnancy, miscarriage, and breastfeeding, among others.
It is recommended that if your symptoms persist or worsen, you should consult a gynecologist to check for hormonal imbalances or other underlying causes.
Thank you! Wishing you peace and health, Dr.

More Info

In your situation, it seems that you are experiencing some uncertainty regarding your menstrual cycle and the possibility of pregnancy. Given that you have had irregular periods since February and have had negative pregnancy tests, it is understandable to feel concerned. Let’s break down your situation and provide some guidance.

Firstly, it’s important to note that a negative pregnancy test, especially when taken correctly using first-morning urine, typically indicates that you are not pregnant. However, there are exceptions, such as very early pregnancy or issues with the test itself. Since you mentioned that you have had three instances of sexual intercourse from February to June, and all were protected with condoms, the likelihood of pregnancy is low, but not impossible.
Irregular periods can be caused by a variety of factors, including stress, hormonal imbalances, changes in weight, or underlying health conditions. At the age of 45, you may also be approaching perimenopause, a transitional phase before menopause where menstrual cycles can become irregular. Symptoms of perimenopause can include changes in menstrual cycle frequency, hot flashes, night sweats, and mood swings.

Given that you have noticed a slight increase in your weight and a feeling of abdominal fullness, it’s important to consider other factors that could contribute to these sensations. Weight gain can occur for many reasons, including dietary changes, decreased physical activity, or hormonal changes. If you are concerned about your weight or the changes in your body, it may be beneficial to consult with a healthcare provider.

If your periods remain irregular, or if you continue to experience symptoms that concern you, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, blood tests to check hormone levels, and possibly an ultrasound to assess your reproductive organs. This can help rule out any underlying conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances.

In summary, while the negative pregnancy tests suggest that you are not pregnant, the irregularity of your menstrual cycle and the changes in your body warrant further investigation. It is always better to err on the side of caution when it comes to your health. Consulting with a healthcare professional will provide you with the necessary guidance and peace of mind. They can help you understand what is happening with your body and suggest appropriate next steps, whether that be lifestyle changes, further testing, or monitoring your symptoms over time.
