Delayed Menstruation: Causes and Pregnancy Concerns

Delayed menstruation

Hello, doctor.
My last menstrual period was from March 7 to March 11, and I was supposed to have my period on April 6, but it hasn't arrived yet.
Last month, between April 12 and April 17, I had several instances of sexual activity with my boyfriend, but it was only with fingers and no penetration.
My boyfriend said he did not ejaculate, and he only used his fingers to enter my vagina.

1) Is there a chance I could be pregnant? Additionally, I have been using a pregnancy test from April 9 to April 11, and all results have been negative.

2) Is there still a possibility of pregnancy? I am currently experiencing breast tenderness and occasional lower abdominal pain, similar to the symptoms I usually have before my period.

3) Does this mean my period is about to start?
4) Is there a chance of pregnancy?
5) Is the pregnancy test accurate at this point?

Understanding delayed menstruation can be a source of anxiety, especially when considering the possibility of pregnancy. Based on your description, let's address your concerns step by step.

1. Possibility of Pregnancy: You mentioned that you had several instances of sexual activity with your boyfriend, but it was only through manual stimulation and that he did not ejaculate. Generally, the risk of pregnancy from manual stimulation is very low, especially if there was no direct ejaculation into the vagina. However, it is important to note that pre-ejaculate fluid can sometimes contain sperm, although the likelihood of this leading to pregnancy is quite low. Given that you have taken multiple home pregnancy tests (HPTs) and they have all returned negative results, it is unlikely that you are pregnant.

2. Timing of Your Menstrual Cycle: Your last menstrual period was from March 7 to March 11, and you expected your next period around April 6. It is not uncommon for menstrual cycles to be irregular, especially if you are experiencing stress, changes in weight, or other lifestyle factors. The symptoms you are experiencing, such as breast tenderness and lower abdominal pain, can indeed be premenstrual symptoms (PMS) that occur before your period starts.
3. Menstrual Symptoms: The breast tenderness and lower abdominal discomfort you are experiencing could indicate that your period is approaching. Many women experience similar symptoms in the days leading up to their menstrual cycle. However, if your period does not arrive soon, it may be worthwhile to consult with a healthcare provider to rule out any underlying issues.

4. Accuracy of Home Pregnancy Tests: Home pregnancy tests are generally quite accurate when used correctly, especially after a missed period. If you have tested negative multiple times and are still experiencing a delayed period, it is unlikely that you are pregnant. However, if your period does not arrive within a week or so, consider retesting or consulting a healthcare professional for a blood test, which is more sensitive and can detect pregnancy earlier than home tests.

5. Next Steps: If your period does not arrive soon and you continue to have symptoms, it would be advisable to see a healthcare provider. They can provide a more comprehensive evaluation, including a physical examination and possibly blood tests to check hormone levels. Additionally, they can help address any concerns you may have regarding your menstrual health and provide guidance on managing any anxiety related to potential pregnancy.

In summary, while the possibility of pregnancy seems low based on your description and negative tests, it is essential to monitor your symptoms and consult with a healthcare professional if your period does not arrive soon. They can provide reassurance and help you understand your menstrual cycle better. Remember, irregular cycles can happen for various reasons, and seeking medical advice can help clarify your situation.
