Why might a pregnancy test not show a positive result?

Hello Doctor, I would like to ask you a few questions.
I am 30 years old, and my menstrual cycle is usually about 28 to 30 days, and it has never been late.
My last menstrual period started on April 15.
I underwent a hysterosalpingography (HSG) on April 23, and the doctor said both fallopian tubes are patent.
However, my period has not arrived yet.
On May 18, I took a pregnancy test, and the doctor said I am not pregnant.
I would like to ask you:
1.
The doctor advised me to have intercourse with my husband on April 28, April 30, and May 2, and then to start taking progesterone for five days starting May 6.
I have heard that taking progesterone can delay the onset of menstruation; is this true?
2.
I would like to know if the contrast agent used during the HSG could affect my upcoming menstrual cycle or the fertilized egg.
3.
Recently, I have been experiencing intermittent lower abdominal cramping, similar to the feeling before my period, but I have never been late.
How can I determine if I am pregnant or if my period is just delayed?
4.
The doctor has prescribed another 7 days of progesterone for me.
Should I continue taking it? (I am concerned that taking it will further delay my menstruation.)

Dear Patient,
Thank you for reaching out with your concerns regarding your menstrual cycle and the possibility of pregnancy. Let's address your questions one by one, while also providing some context about the factors that can influence pregnancy test results.

1. Effect of Progesterone on Menstrual Cycle: You mentioned that your doctor prescribed progesterone (黄体素) starting from May 6 for five days. Progesterone is a hormone that plays a crucial role in regulating the menstrual cycle and maintaining early pregnancy. When taken, it can indeed delay the onset of menstruation. This is because progesterone helps to maintain the uterine lining, which can prevent the shedding that occurs during menstruation. If you are not pregnant, the withdrawal of progesterone after completing the course may trigger your period. Therefore, if your doctor has advised you to take it, it is essential to follow their guidance, especially if they suspect that you may be pregnant.

2. Impact of Hysterosalpingography (HSG) on Menstrual Cycle: HSG is a procedure used to examine the fallopian tubes and uterus. The contrast dye used during the procedure is generally safe and does not have a lasting impact on your menstrual cycle or the fertilization process. However, some women may experience mild cramping or spotting after the procedure, which is usually temporary. If you have concerns about any unusual symptoms following the HSG, it’s best to discuss them with your healthcare provider.

3. Understanding Abdominal Pain and Menstrual Delay: The cramping you are experiencing in your lower abdomen could be related to several factors, including hormonal changes, the recent HSG procedure, or the potential onset of your period. It can be challenging to differentiate between early pregnancy symptoms and premenstrual symptoms, especially if your cycle is irregular. If your period does not arrive soon and you continue to experience symptoms, it may be worthwhile to take another pregnancy test or consult your doctor for further evaluation.

4. Continuation of Progesterone: Regarding the additional seven days of progesterone prescribed by your doctor, it is crucial to follow their instructions. If your doctor believes that continuing progesterone is necessary for your situation, it is likely because they want to support a potential pregnancy or regulate your cycle. If you have concerns about the effects of progesterone on your menstrual cycle, it’s best to discuss these with your healthcare provider, who can provide personalized advice based on your medical history and current situation.

In summary, there are several reasons why you might not be getting a positive pregnancy test despite a missed period. Factors such as the timing of the test, the sensitivity of the test used, and hormonal influences from medications like progesterone can all play a role. If your period does not arrive soon, or if you continue to have concerns, I recommend scheduling a follow-up appointment with your healthcare provider for further evaluation and guidance.

Wishing you the best of luck, and I hope for a positive outcome for you.

Best regards.
