Menstruation is delayed?


Hello, doctor.
My last menstrual period started on February 8, and my cycle is approximately 30 days.
I have taken two home pregnancy tests, both of which showed a faint line with no color.
I also visited a gynecologist for a pregnancy test, which confirmed that I am not pregnant.
During the ultrasound, the doctor mentioned that my uterine lining is thicker, which could indicate a possible pregnancy or that my period is about to start.
However, it has now been about a week since my period was due, and I have been experiencing a dull, stabbing pain in my abdomen.
This morning, when I went to the bathroom, I noticed a small amount of light pink blood on the toilet paper, but I haven't seen any more throughout the day.
Is there a possibility that I could be pregnant?

Understanding delayed menstruation can be quite perplexing, especially when there are conflicting signs and symptoms. Based on your description, it seems you are experiencing a delay in your menstrual cycle, which can indeed be a sign of pregnancy, but there are also other factors to consider.

Firstly, let's clarify the situation regarding your menstrual cycle. You mentioned that your last menstrual period (LMP) was on February 8th, and your cycle typically lasts around 30 days. This means that you would expect your next period to start around March 10th. Given that you are now a week late, it is understandable that you are concerned about the possibility of being pregnant.

You have conducted home pregnancy tests, which showed faint lines, and a visit to the obstetrician confirmed a negative pregnancy test. However, the ultrasound indicated that your uterine lining is thicker than usual, which can be a sign of early pregnancy or hormonal changes that may precede menstruation. The presence of a faint line on a home pregnancy test can sometimes indicate a very early pregnancy, but it can also be a result of testing too early or even a chemical pregnancy, where the pregnancy does not progress.

The symptoms you described, such as the dull, stabbing pain in your abdomen and the light pink spotting, could be indicative of several things. Spotting can occur for various reasons, including implantation bleeding if you are pregnant, or it could be a sign that your period is about to start. The timing of the spotting is crucial; if it occurs around the time you would expect your period, it may simply be the onset of menstruation.

In terms of the possibility of pregnancy, it is indeed still possible, especially given the thickened uterine lining. However, since you have had negative tests, it is also important to consider other factors that could lead to a delayed period. Stress, hormonal imbalances, changes in weight, and underlying medical conditions such as polycystic ovary syndrome (PCOS) can all affect your menstrual cycle.

If your period does not arrive soon, I would recommend following up with your healthcare provider. They may suggest a blood test for pregnancy, which is more sensitive than home urine tests and can provide a more definitive answer. Additionally, they may want to investigate other potential causes for your delayed menstruation and symptoms.

In conclusion, while there is a possibility of pregnancy given your symptoms and the ultrasound findings, it is equally important to consider other factors that could be influencing your menstrual cycle. Monitoring your symptoms and maintaining open communication with your healthcare provider will be key in determining the next steps. If you experience any severe pain, heavy bleeding, or other concerning symptoms, seek medical attention promptly.
