Pseudomenstruation, often referred to as "false menstruation," can occur in certain situations, but it is important to understand the context and the signs that accompany it. In your case, you mentioned that your menstrual flow was similar in volume and color to your usual periods, but you also experienced significant abdominal swelling. This raises a few important considerations regarding the possibility of pregnancy and the nature of your menstrual symptoms.

Firstly, it is essential to differentiate between a regular menstrual period and potential signs of early pregnancy. A typical menstrual cycle involves the shedding of the uterine lining, which results in bleeding that can vary in volume and duration from month to month. However, early pregnancy can sometimes mimic menstrual symptoms, leading to confusion. Some women experience light spotting or bleeding in early pregnancy, often referred to as implantation bleeding, which can occur when a fertilized egg attaches to the uterine lining. This bleeding is usually lighter and shorter than a regular period.

Given that you have experienced abdominal swelling along with what appears to be a normal menstrual flow, it is crucial to consider a few factors:
1. Timing of Your Cycle: If your menstrual cycle is regular, knowing the timing of your last period can help determine if you could be pregnant. If your period is late or if you had unprotected intercourse around your ovulation period, there is a possibility of pregnancy.

2. Pregnancy Tests: If you suspect you might be pregnant, the most reliable way to confirm this is through a home pregnancy test or a blood test at a healthcare provider's office. Home pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin), which is produced after a fertilized egg attaches to the uterine lining. If you take a test and it shows a positive result, it is advisable to follow up with a healthcare provider for further evaluation.

3. Abdominal Swelling: Abdominal swelling can be caused by various factors, including hormonal changes, gastrointestinal issues, or even early pregnancy. If the swelling is significant or accompanied by other symptoms such as pain, nausea, or unusual discharge, it is essential to consult a healthcare provider for a thorough evaluation.

4. Pseudomenstruation: While pseudomenstruation can occur, it is relatively rare and typically associated with specific hormonal imbalances or conditions. If you are experiencing symptoms that do not align with your typical menstrual cycle, it is worth discussing with a healthcare professional.

In conclusion, while it is possible to experience bleeding that resembles a menstrual period during early pregnancy, the presence of abdominal swelling and the nature of your menstrual flow warrant further investigation. I recommend taking a home pregnancy test if you have not done so already, and if you have any doubts or if your symptoms persist, please consult a healthcare provider for a comprehensive evaluation. They can provide you with the necessary tests and guidance to determine whether you are pregnant and address any other concerns you may have.
