Menstrual Delays and Pregnancy Symptoms in Women - Obstetrics and Gynecology

I'm sorry, but I cannot assist with that?


Two days ago, I felt like my period was about to start because on Thursday I suddenly noticed my abdomen felt a bit larger, and my breasts were painful when pressed.
Recently, I haven't experienced any abdominal pain, nausea, or vomiting, except for some abdominal pain after doing sit-ups and running yesterday.
Other than that, I haven't had any issues.
My period is about a week late now, and it still hasn't arrived.
The encounter was through intercourse, and I did not masturbate, but I was concerned that there might have been contact with pre-ejaculate fluid that could have entered the vagina.
I want to ask the doctor about a previous situation where he took medication to induce menstruation; he mentioned that after taking it, his periods were normal for two months, and after taking it again, they were normal for three months, but he hasn't taken any inducing medication since then.
Is this delay normal, especially considering he has polycystic ovary syndrome (PCOS)? If he is pregnant, shouldn't he feel a gradual increase in abdominal size rather than a sudden change? Can we determine that this is just a sign that his period is about to start? You mentioned that the probability is almost negligible; is it still necessary to take a pregnancy test? Typically, how long does it take from feeling like the period is coming to actually starting?

My period is about a week late now, and it still hasn't arrived.
The encounter was through intercourse, and I did not masturbate, but I was concerned that there might have been contact with pre-ejaculate fluid that could have entered the vagina.
I would like to ask the doctor about my partner, who previously took medication to induce menstruation.
He mentioned that after taking it, his periods were normal for two months, and after taking it again, they were normal for three months, but he hasn't taken any inducing medication since then.
Is it normal for his period to be delayed this time, especially considering he has polycystic ovary syndrome?
Answer: It's not necessarily normal.
If he is pregnant, would he not suddenly feel his abdomen getting larger? Shouldn't it gradually increase in size?
Answer: In pregnancy, the abdomen does gradually enlarge.
Can we confirm that this is just a sign that his period is about to start?
Answer: You mentioned that the likelihood is almost negligible; is it still necessary to take a pregnancy test?
Answer: A pregnancy test is not needed.
Typically, how long does it take from feeling symptoms to the arrival of menstruation?
Answer: It varies.

Understanding menstrual delays and pregnancy symptoms can be quite complex, especially for women who are trying to conceive or have irregular menstrual cycles. Based on your description, it seems you are experiencing a delay in your menstrual cycle, which can be influenced by various factors, including hormonal changes, stress, and underlying health conditions such as polycystic ovary syndrome (PCOS).

Firstly, it’s important to note that a missed period can be one of the earliest signs of pregnancy, but it is not definitive on its own. Many women experience menstrual irregularities for reasons unrelated to pregnancy. In your case, since you have a history of PCOS, this condition can lead to irregular cycles and missed periods. PCOS is characterized by hormonal imbalances that can affect ovulation, leading to delayed or absent menstruation. Therefore, it is possible that your missed period is related to your underlying condition rather than pregnancy.

Regarding your symptoms, feeling a sensation of abdominal enlargement and breast tenderness can occur in early pregnancy, but these symptoms can also be associated with premenstrual syndrome (PMS) or other hormonal fluctuations. It is not uncommon for women to experience changes in their bodies that can be mistaken for pregnancy symptoms, especially when they are anxious about conceiving.
You mentioned that you have not experienced nausea or vomiting, which are common early pregnancy symptoms. Additionally, the fact that you have had a delay of about a week could suggest that it might be time to take a pregnancy test. However, if you have taken a test and it has come back negative, it may be too early to detect pregnancy, especially if you ovulated later than expected. Pregnancy tests are most accurate when taken after a missed period, so if you continue to experience a delay, it would be advisable to test again in a few days.

As for the concern about your partner's previous use of medication to induce menstruation, it is important to understand that such medications can sometimes lead to temporary changes in menstrual patterns. If he has not taken these medications recently, it is less likely that they would affect your cycle now.

In terms of your question about whether pregnancy would cause a sudden feeling of abdominal enlargement, typically, any noticeable changes in abdominal size due to pregnancy occur gradually over time. Early pregnancy may cause some bloating or a feeling of fullness, but significant changes in abdominal size usually develop later in the pregnancy.

Lastly, if you are feeling uncertain about your symptoms or the possibility of pregnancy, it is always a good idea to consult with a healthcare provider. They can offer personalized advice, conduct necessary tests, and help you understand your menstrual cycle better. If you are experiencing significant discomfort or have concerns about your reproductive health, seeking medical advice is essential.

In summary, while a missed period can indicate pregnancy, it is not the only explanation, especially with a history of PCOS. Monitoring your symptoms, taking a pregnancy test after a missed period, and consulting with a healthcare professional will provide clarity and help you navigate your concerns effectively.
