Pregnancy Chances: Thick Endometrium and Symptoms Explained

Probability of Pregnancy

Hello doctor, I have a question.
I am currently planning for pregnancy, and my menstrual cycle is quite regular, with a maximum variation of two days.
I usually have noticeable symptoms before my period starts.
My last menstrual period began on November 27, but I have not had it this month.
Starting on December 28, I began to experience significant lower abdominal pain.
That night, I felt weakness in my legs, chills, and continued to have a fever, which persisted into the 29th with a temperature ranging from 37.4 to 37.8 degrees Celsius.
However, I did not have a sore throat or headache, so I ruled out the possibility of a cold.
On the night of the 29th, I bought a pregnancy test, but it was negative.
My lower abdominal pain persisted, but the fever symptoms subsided.
I decided to visit a gynecologist to check for possible uterine inflammation or infection.
On the 30th, I went to a nearby gynecology clinic, and the pregnancy test was also negative.
The doctor performed an ultrasound and asked if my menstrual cycles were regular, to which I confirmed they were.
The doctor noted that my endometrium was thick and asked if I would like to continue with a pregnancy if I were to conceive.
I expressed my desire to do so, especially since I have been trying to conceive for four years without success.
The doctor advised me to wait a week and then retest for pregnancy.
I would like to ask the doctor what it means for the endometrium to be thick around the time of my expected period (as I have not experienced this before).
Additionally, I would like to know what the chances of pregnancy are in this situation.
Thank you, doctor, for taking the time to respond.
I appreciate your help.

It is recommended to follow your doctor's advice and return for an examination to confirm whether or not you are pregnant.

Understanding your situation regarding potential pregnancy and the implications of a thickened endometrium is essential, especially after trying to conceive for an extended period. Based on your description, it seems you are experiencing some unusual symptoms and changes in your menstrual cycle, which can be concerning.

Firstly, a thickened endometrium (the lining of the uterus) can indicate several things. In a typical menstrual cycle, the endometrium thickens in preparation for a potential pregnancy. If pregnancy does not occur, the lining sheds during menstruation. A thickened endometrium before your expected period could suggest that your body is preparing for a pregnancy, especially if you are experiencing symptoms like abdominal pain and other signs of potential hormonal changes. However, it can also be a sign of other conditions, such as hormonal imbalances, uterine fibroids, or even endometrial hyperplasia, which is an overgrowth of the endometrial lining.

Given that you have been trying to conceive for four years without success, it is understandable to feel anxious about your current symptoms. The fact that you experienced a fever and other systemic symptoms could indicate an underlying infection or inflammation, which may also affect your reproductive health. It is crucial to rule out any infections or other medical conditions that could impact your ability to conceive.

Regarding your question about the likelihood of pregnancy with a thickened endometrium, it is generally considered a positive sign, as it indicates that your body is responding appropriately to hormonal signals. However, the actual chances of conception depend on several factors, including the timing of ovulation, the health of your eggs and sperm, and the overall health of your reproductive system. Since you mentioned that you have been tracking your menstrual cycle and have a regular pattern, it is essential to continue monitoring for ovulation signs, such as changes in cervical mucus or basal body temperature.

The recommendation from your doctor to wait a week and retest for pregnancy is prudent. If your period does not arrive, a follow-up pregnancy test can provide more clarity. If the test remains negative and your symptoms persist, further evaluation may be warranted. This could include blood tests to check hormone levels, a more detailed ultrasound to assess the endometrium and ovaries, or even a referral to a fertility specialist if necessary.

In summary, while a thickened endometrium can be a positive sign for potential pregnancy, it is essential to consider the broader context of your health and any symptoms you are experiencing. If you continue to have concerns or if your symptoms worsen, seeking further medical advice is crucial. Your health and well-being are paramount, and addressing any underlying issues will be beneficial for your fertility journey.
