Are you pregnant?


Hello Doctor: My menstrual cycle has never been very regular, and sometimes I even miss a month.
I had sexual intercourse on November 18, 19, and December 2 and 9.
(There was only foreplay on the male side without a condom; the rest were protected.) This month, since I planned to go on a trip, I visited a gynecologist on December 6 for a pregnancy test and ultrasound, which showed that I was not pregnant.
However, since the 9th was too close, the doctor said it couldn't be detected and could only test for the 2nd.
After the test, the doctor prescribed medication to induce my period because my last menstrual period was on November 4.
The gynecologist prescribed progesterone for me to take, and since I would be traveling from the 16th to the 22nd, the doctor advised me to take one Meterone tablet four times a day (one every four hours) and that my period should come in about 3 to 5 days.
However, my period did not come, which made me very worried.
So on December 15, I went back to the gynecologist for another urine test and ultrasound, which again showed that I was not pregnant.
After returning from my trip, on December 23, I visited the gynecologist again, and the urine test and ultrasound still showed no pregnancy.
I would like to ask the doctor, what is the likelihood of me being pregnant? I read online that not getting my period after taking progesterone could indicate a possible pregnancy, which makes me very anxious.
Should I get a blood test to check for pregnancy? Additionally, I took medication for a urinary tract infection for about a week (from December 10 to 15).
I kindly ask for your guidance, as I am really very worried.
Thank you, Doctor.

Hello, concerned woman: It sounds like you are not pregnant.
Sometimes, even after taking menstrual induction medication, menstruation may still be delayed, which is quite common in clinical practice.
As long as you confirm that you are not pregnant through a urine or blood test, you can take the menstrual induction medication again or receive an injection.

More Info


Understanding pregnancy concerns, especially in the context of irregular menstrual cycles, can be quite complex and anxiety-inducing. Based on the details you've provided, it seems that you've been actively monitoring your menstrual cycle and have sought medical advice multiple times, which is a positive step. Let's break down your situation and address your concerns regarding the possibility of pregnancy, the effects of medications, and the implications of irregular periods.


Irregular Periods and Pregnancy Testing
Irregular menstrual cycles can complicate the process of determining whether or not you are pregnant. Since your periods are not regular, it can be challenging to pinpoint ovulation and the timing of potential conception. The fact that you have had unprotected sexual encounters during your cycle does raise the possibility of pregnancy, but it is important to consider the timing of your tests.

You mentioned that you had a urine pregnancy test and an ultrasound on December 6, and both were negative. Given that the tests were conducted relatively early in your cycle, it is possible that they may not have detected a pregnancy if conception occurred shortly before or after the tests. However, since you have had multiple negative tests and ultrasounds, the likelihood of being pregnant decreases significantly.


The Role of Medications
You were prescribed progesterone (Meterone Tablets) to help induce your period. Progesterone is often used to regulate menstrual cycles and can sometimes delay menstruation if you are pregnant. However, it is also common for individuals to experience a delay in their period even after taking progesterone, especially if there are underlying hormonal imbalances or other factors at play.

If you are concerned that the progesterone may have affected your ability to detect pregnancy, it is worth noting that while progesterone can delay menstruation, it does not cause pregnancy. If you are still experiencing anxiety about the possibility of being pregnant, a blood test for beta-hCG (the hormone produced during pregnancy) can provide a more definitive answer than a urine test, especially if it is performed a week or so after your missed period.


Additional Considerations
1. Urinary Tract Infection (UTI) Treatment: You mentioned taking medication for a urinary tract infection. Generally, antibiotics for UTIs do not affect pregnancy tests, but it is always good to inform your healthcare provider about all medications you are taking.

2. Symptoms to Monitor: If you experience any unusual symptoms such as severe abdominal pain, heavy bleeding, or other concerning signs, it is crucial to seek medical attention promptly.

3. Follow-Up Testing: If your period does not arrive after completing the course of progesterone, or if you continue to have concerns about pregnancy, it is advisable to return to your healthcare provider for further evaluation. A blood test can confirm or rule out pregnancy more accurately than urine tests, especially in cases of irregular cycles.

4. Emotional Well-Being: It is completely normal to feel anxious about potential pregnancy, especially when dealing with irregular cycles and medication. Consider discussing your feelings with a healthcare professional who can provide support and guidance.

In conclusion, while the chances of being pregnant seem low given the negative tests and ultrasounds, if you remain concerned, a blood test can provide clarity. Irregular periods can be frustrating, but with proper medical guidance, you can navigate this uncertainty more effectively. Always feel empowered to communicate openly with your healthcare provider about your concerns and any symptoms you may be experiencing.
