Nausea during menstruation?


Hello Doctor, I would like to ask about my last menstrual period, which started on December 4 and ended on December 9.
After that, I had unprotected intercourse from December 16 to December 18 and again from December 30 to January 1.
My period in January was four days late, and I have been experiencing continuous abdominal pain along with feelings of nausea.
Two days ago, my discharge was brown with a bit of pink, and after two days, it turned into a normal menstrual flow with many blood clots.
I am still feeling nauseous.
Is it possible that this could be a sign of pregnancy or implantation bleeding? If I want to take a pregnancy test, should I wait until the bleeding has completely stopped? Thank you, Doctor, for your response.

Ms. Huang, 20~29 year old female. Ask Date: 2023/01/11

When it comes to understanding menstrual symptoms and potential signs of pregnancy, several factors need to be considered, especially in the context of your recent experiences. Based on your description, you had your last menstrual period (LMP) on December 4, which lasted until December 9. You then engaged in unprotected sexual intercourse on December 16-18 and December 30-January 1. You mentioned that your period was late by four days, and you have been experiencing abdominal pain and nausea, along with unusual discharge that was brownish with a hint of pink, followed by a heavier flow with blood clots.

Firstly, it is important to note that nausea and abdominal pain can be symptoms associated with both premenstrual syndrome (PMS) and early pregnancy. PMS can cause a variety of symptoms, including mood swings, bloating, breast tenderness, and nausea, which can sometimes mimic the early signs of pregnancy. On the other hand, early pregnancy symptoms can also include nausea (often referred to as morning sickness), fatigue, and changes in discharge.

The brownish discharge you experienced could potentially be indicative of implantation bleeding, which occurs when a fertilized egg attaches to the uterine lining. This type of bleeding is usually lighter than a regular menstrual period and can be accompanied by mild cramping. However, the presence of blood clots and a heavier flow following this discharge suggests that you may have experienced your menstrual period rather than implantation bleeding.

Given that your menstrual cycle is typically around 28-31 days, a delay of four days could be significant, especially if you have had unprotected intercourse during your fertile window. If you suspect that you might be pregnant, it is advisable to take a home pregnancy test. Most tests are sensitive enough to detect pregnancy hormones (hCG) about a week after a missed period. However, if you are currently experiencing bleeding, it may be best to wait until the bleeding has completely stopped before taking a test for the most accurate result.

In summary, while nausea and abdominal pain can be signs of both PMS and early pregnancy, the presence of a heavier menstrual flow with blood clots suggests that you may be experiencing your period rather than early pregnancy symptoms. If your symptoms persist or if you have any concerns about your menstrual cycle or potential pregnancy, it is important to consult with a healthcare provider for further evaluation and guidance. They can provide personalized advice based on your medical history and current symptoms, ensuring that you receive the appropriate care.
