Delayed Periods and Pregnancy Testing Concerns

Menstrual delay and pregnancy testing issues?

My last menstrual period started on March 16, and my cycle typically ranges from 30 to 35 days.
About 13 days ago, I began experiencing premenstrual symptoms such as breast enlargement and fatigue, but my period still hasn't arrived, and it is already two days late compared to the app's expected date of April 15.
In the last two days, I've also felt a sense of abdominal discomfort and the sensation of something wanting to come out, and I noticed a small amount of light yellowish-brown discharge in my underwear.

I had three instances of sexual intercourse during the app's designated fertile window at the end of March (with protection), and I'm worried that this might have led to pregnancy, causing symptoms similar to early pregnancy before my period.
However, I also had sexual intercourse on April 7, 8, 12, and 14.
Given my concerns about the possibility of pregnancy from intercourse during the fertile window, I took a morning urine pregnancy test today (16 days after the risky sexual encounters).

1️⃣ However, since I had sexual intercourse on April 7, 8, 12, and 14, I am unsure if there is a possibility of pregnancy from April 7 that could explain my missed period and whether the short time frame might affect the accuracy of the test results.

2️⃣ When I checked the test within ten minutes in the bathroom, I thought I saw a very faint second line, but I wasn't sure.
Later, when I returned to the room a few minutes later, I couldn't see the line anymore.
Does the line fade over time? Is there a possibility of pregnancy from the sexual encounters at the end of March?
3️⃣ I've been experiencing abdominal discomfort and the sensation of something wanting to come out for the past few days, and I noticed a small amount of light yellowish-brown discharge in my underwear.
Could this indicate that my period is about to start?
I would appreciate it if you could answer these three questions.
I'm really worried! Thank you.

Hello, you can take a pregnancy test 12 days after sexual intercourse.
The chances of pregnancy should be low.
If your period still hasn't arrived after another week, it is advisable to see a gynecologist.
Wishing you good health.

More Info

Understanding delayed periods and the concerns surrounding pregnancy testing can be quite stressful, especially when there are multiple factors at play. Based on your description, let’s break down your situation and address your questions systematically.

1. Possibility of Pregnancy
Given that your last menstrual period started on March 16 and your cycle typically ranges from 30 to 35 days, you would expect your next period around April 15 to April 21. Since you are currently experiencing a delay of two days, it is understandable to be concerned about the possibility of pregnancy, especially since you had unprotected intercourse during your fertile window at the end of March.

However, it’s important to note that while you had sexual encounters during your fertile window, the use of condoms significantly reduces the likelihood of pregnancy. If the condom was used correctly and did not break or slip, the risk of pregnancy is low.

2. Timing of Pregnancy Tests
You mentioned that you took a pregnancy test using morning urine, which is typically the most concentrated and reliable for detecting pregnancy hormones (hCG). Since you had sexual encounters on April 7, 8, 12, and 14, it is possible that if conception occurred, it would be detectable by now, especially since it has been over two weeks since the last potential conception date.

Regarding the faint second line you observed on the test, it is crucial to interpret this correctly. A faint line can indicate a positive result, but it is also possible for evaporation lines to appear if the test is read after the recommended time frame. If you saw the line within the time limit (usually within 3-5 minutes), it may be a positive result. However, if it disappeared after a few minutes, it is likely an evaporation line, which does not indicate pregnancy.

3. Physical Symptoms and Menstrual Cramps
The symptoms you are experiencing, such as breast tenderness, fatigue, and abdominal discomfort, can be associated with both premenstrual syndrome (PMS) and early pregnancy. The presence of light yellowish discharge could be related to hormonal changes in your body as it prepares for menstruation or could be an early sign of pregnancy.
The cramping sensation and the feeling of something about to flow out are common premenstrual symptoms. If your period does not arrive soon, it would be advisable to retest in a few days or consult with a healthcare provider for further evaluation.

Conclusion
In summary, while there is a possibility of pregnancy due to the timing of your sexual activity, the use of condoms significantly reduces this risk. The faint line on your pregnancy test requires careful interpretation, and if you are still uncertain, consider retesting in a few days or consulting a healthcare professional. Your physical symptoms could indicate that your period is approaching, but if the delay continues, further investigation may be warranted to rule out any underlying issues such as hormonal imbalances or stress-related factors, which can also affect menstrual cycles.

If you have any further questions or concerns, please do not hesitate to reach out to a healthcare provider for personalized advice and support.
