Missed Period and Negative Pregnancy Test: What to Do Next?

No menstruation and not pregnant?

Hello Dr.
Chang, my period was due on April 19, but it still hasn't arrived.
I went to see a doctor on April 25 for a pregnancy test, which came back negative, and I received an injection and medication, but my period still hasn't come.
The doctor said it might take a week after the injection for my period to start.
Why is that? Additionally, I've been experiencing persistent abdominal discomfort and lower back pain.
Should I go back for another visit? Thank you.

Hello, the factors that can affect the menstrual cycle or cause intermenstrual bleeding are numerous, including environment, lifestyle, stress, emotional instability, diet, age, lesions in the uterus or cervix, and pregnancy, among others.
After taking menstrual induction medication, it may take several days for the withdrawal response to occur before menstruation begins.
If symptoms persist or worsen, it is important to consult a physician for examination and treatment.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info

When dealing with a missed period and a negative pregnancy test, it’s important to understand the various factors that could be at play. In your case, you mentioned that your period was due on April 19, but it has not arrived, and you took a pregnancy test on April 25 that came back negative. You also mentioned experiencing abdominal discomfort and lower back pain.
Firstly, it’s essential to recognize that a missed period can be caused by a variety of factors, including stress, hormonal imbalances, changes in weight, excessive exercise, or underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders. Given that you have already consulted a doctor and received treatment, it’s crucial to follow their advice closely.

The fact that your pregnancy test was negative is a good indicator that you are not pregnant, especially if you took the test after your missed period. Home pregnancy tests are generally reliable, but they can sometimes yield false negatives, particularly if taken too early or if the test is not used correctly. However, since you have already consulted a physician and received a negative test result, it is likely that pregnancy is not the issue.

You mentioned that your doctor prescribed medication and injections, which may be intended to help regulate your menstrual cycle. It’s common for doctors to administer hormonal treatments to induce a period, especially if there is a concern about irregular cycles. The reason your doctor indicated that it might take a week for your period to arrive after the treatment is that hormonal changes can take time to manifest in your body. The medications may help to stimulate the lining of the uterus to shed, leading to menstruation.

As for the abdominal discomfort and lower back pain you are experiencing, these symptoms can be associated with a variety of conditions, including premenstrual syndrome (PMS), ovulation pain, or even stress-related tension. If the pain is severe or persistent, it is advisable to reach out to your healthcare provider for further evaluation. They may want to perform additional tests or examinations to rule out any underlying issues.

In summary, here are the steps you should consider taking next:
1. Follow Up with Your Doctor: If you have not seen any improvement or if your symptoms worsen, it’s important to return to your healthcare provider. They can reassess your situation and may perform further tests to ensure there are no underlying health issues.

2. Monitor Your Symptoms: Keep track of any additional symptoms you may experience, such as changes in pain intensity, any unusual discharge, or other menstrual irregularities. This information can be helpful for your doctor.

3. Be Patient with the Treatment: Understand that hormonal treatments can take time to work. It may take a few days to a week for your body to respond to the medication.

4. Lifestyle Considerations: Consider factors that may be affecting your menstrual cycle, such as stress, diet, and exercise. Making healthy lifestyle choices can positively impact your menstrual health.

5. Seek Support: If you are feeling anxious or stressed about your situation, consider talking to a friend or a mental health professional. Emotional well-being is an important aspect of overall health.

In conclusion, while a missed period and negative pregnancy test can be concerning, there are many potential explanations. Following your doctor’s advice and keeping an open line of communication with them will help you navigate this situation effectively.
