Patient's question:
I have always had a regular menstrual cycle, with a period of about 30-33 days. On November 30, 2005, I had my period, but I have not had another period since then. During the period from December 20 to 30, there was an instance of unprotected intercourse. I took early pregnancy tests on January 6, 8, and 19 (from different manufacturers), and all of them were negative.Does this mean I am not pregnant? What could be the reason for my missed period? Thank you very much!
First follow-up question: So far, I haven’t experienced any early pregnancy symptoms such as nausea, vomiting, or frequent urination, but I do have a slight lower abdominal pain.
Second follow-up question
Doctor's answer:
That could be due to not being pregnant, birth control pills, or issues related to mood, causing menstrual irregularities. Mood, medication, food, environment, and other factors can all lead to menstrual irregularities.
