Delayed Menstruation: Causes and Remedies Explained

Missed menstruation?

Hello Doctor, my last menstrual period was on November 28.
Since then, as of January 10, I have not had my period.
I have had sexual intercourse with my boyfriend using protection.
On January 4, I visited a gynecologist and had a pregnancy test and ultrasound, which showed no pregnancy.
The doctor prescribed me a three-day course of medication to induce my period, but I still haven't gotten my period after taking it.
On January 7, feeling a bit anxious and impatient, I went for an injection to induce my period after another pregnancy test and ultrasound.
As of January 10, I still have not had my period.

I have a few questions:
1.
Will taking the medication to induce my period on January 4 and receiving the injection on January 7 have any effects on my body? Could it delay or advance my menstrual cycle?
2.
I have tested for pregnancy at two clinics and also at home, and all tests have shown negative results.
Since I have used protection during intercourse with my boyfriend, is there still a chance that I could be pregnant?
3.
Given that I took the medication on January 4 and received the injection on January 7, when can I expect my period to arrive?

Hello, based on your description, the likelihood of side effects from menstrual induction medications and injections is relatively low.
However, there is still about a 5% failure rate with the correct use of condoms, which means there is still a possibility of pregnancy.
Generally, it is not recommended to rely solely on condoms for contraception.
I suggest that if you do not get your period one week after receiving the injection, you should consult a physician to check for pregnancy.
Thank you! Wishing you peace and health.

More Info

Understanding delayed menstruation can be a complex issue, as it can stem from various factors including hormonal imbalances, stress, lifestyle changes, and underlying health conditions. In your case, you have already taken steps to investigate the cause of your delayed menstruation by consulting with a gynecologist and undergoing pregnancy tests, which have returned negative results.
1. Impact of Medications: You mentioned that you took medication to induce menstruation on January 4th and received an injection on January 7th. These medications, typically containing hormones, are designed to help regulate your menstrual cycle. While they can be effective in prompting menstruation, they may also cause temporary changes in your cycle. The use of these medications does not typically delay your period further; rather, they are intended to induce it. However, individual responses can vary. Some women may experience a delay in their cycle due to the hormonal adjustments, while others may find that their period arrives shortly after treatment. It’s important to monitor your body’s response and communicate any concerns with your healthcare provider.

2. Pregnancy Concerns: You have taken multiple pregnancy tests, both at clinics and at home, all of which have returned negative results. Additionally, you mentioned that you and your boyfriend have consistently used condoms during sexual intercourse. While no contraceptive method is 100% effective, the use of condoms significantly reduces the risk of pregnancy. Given the negative tests and the use of protection, it is unlikely that you are pregnant. However, if you continue to have concerns, it may be worth discussing further testing options with your healthcare provider.

3. When to Expect Your Period: After taking the medication and receiving the injection, the timing of your period can vary. Generally, if the medications are effective, you may expect your period to arrive within a few days to a week after the last dose. However, if you do not see any signs of menstruation within a week or so after your last treatment, it is advisable to follow up with your healthcare provider. They may want to conduct further evaluations to rule out any underlying issues that could be contributing to your delayed menstruation.

In summary, while hormonal treatments can help induce menstruation, individual responses can vary, and it may take some time for your body to adjust. If your period does not arrive soon, or if you experience any unusual symptoms, it is crucial to seek further medical advice. Your healthcare provider can offer additional insights and potential next steps, which may include further testing or alternative treatments to help regulate your menstrual cycle. Remember, maintaining open communication with your healthcare provider is key to addressing any concerns you may have regarding your reproductive health.
