I took a menstrual induction medication after being late for more than twenty days?


The last menstrual period was from June 1 to June 6, and there was sexual intercourse at least twice a week, primarily without ejaculation.
Later, I noticed a delay in my period, and then there were a few instances of ejaculation.
After about ten days, I took a pregnancy test which showed one line, and still did not get my period, so I tested again with the same result.
On July 26, I visited a gynecologist and had a quick ultrasound, and I was given medication to induce menstruation.
My next menstrual period was from January 31 to February 4.
After that, I fell ill, and my period did not return until March 30.
Is it normal for such a long gap in between periods? Could the medication have affected it? During the wait for my July period, I took over-the-counter cold medication, but I do not have a prescription to check what I took.
Could this also cause a delay, or is it possible that I have ovarian dysfunction? Or could it be premenstrual tension or premenstrual syndrome? I have considered many reasons and researched a lot of information, but I still cannot find clarity.
Thank you, doctor.

Hello, the factors that can affect the menstrual cycle are numerous, including age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraceptive pills, diet, polycystic ovary syndrome, lesions of the uterus or cervix, infections, ovulation, pregnancy, and breastfeeding, among others.
It is advisable to consult a gynecologist if symptoms persist or worsen to determine if there is a hormonal imbalance or other underlying causes.
Thank you! Wishing you peace and health, Dr.

Understanding delayed menstruation can be complex, as it involves various physiological, hormonal, and lifestyle factors. Based on your description, it seems you have experienced irregular menstrual cycles, which can be attributed to several potential causes.

Firstly, it's important to note that the menstrual cycle can be influenced by a range of factors, including stress, illness, hormonal imbalances, and medications. In your case, you mentioned that you had a significant delay in your menstrual cycle after your last period in June, followed by a visit to a gynecologist who prescribed medication to induce menstruation. This suggests that your body may not have been producing the necessary hormones to trigger a menstrual cycle on its own.

One common cause of delayed menstruation is hormonal imbalance. The menstrual cycle is regulated by a delicate interplay of hormones, including estrogen and progesterone. If there is an imbalance, it can lead to irregularities in the cycle. Factors such as stress, significant weight changes, excessive exercise, or underlying health conditions (like polycystic ovary syndrome or thyroid disorders) can disrupt this hormonal balance.

You also mentioned experiencing an illness, which can further complicate matters. Illness can lead to physical stress on the body, which may affect the hypothalamus and pituitary gland's ability to regulate hormones properly. This can result in delayed or missed periods.

Regarding the medications you took, while some medications can influence menstrual cycles, over-the-counter cold medications typically do not have a direct effect on menstrual timing. However, if you were taking any prescription medications or if the cold medication contained ingredients that could affect hormonal levels (like certain antihistamines), it might be worth discussing with your healthcare provider.

Another factor to consider is premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD). These conditions can cause significant emotional and physical symptoms leading up to menstruation, which may also contribute to the perception of irregular cycles. Stress and anxiety can exacerbate these symptoms, potentially leading to further delays in menstruation.

In your case, since you have already consulted with a gynecologist and received treatment to induce menstruation, it would be advisable to monitor your cycle closely moving forward. If your periods continue to be irregular or if you experience additional symptoms such as severe pain, excessive bleeding, or other concerning signs, a follow-up appointment with your healthcare provider would be warranted. They may recommend further testing, such as blood tests to check hormone levels or imaging studies to assess ovarian function.

In summary, delayed menstruation can result from a variety of factors, including hormonal imbalances, stress, illness, and medications. It is essential to maintain open communication with your healthcare provider and report any ongoing concerns or changes in your menstrual cycle. Keeping a menstrual diary, noting any symptoms, stressors, and medications taken, can also be helpful for your healthcare provider in determining the underlying cause of your irregular cycles.
