Patient's question:
Patient Age: 24Dear Doctor,
I usually have a 27-day menstrual cycle. My last period was on December 4, but it didn't arrive by December 31. From December 31 to January 11, I had sexual intercourse, stopping on the 11th. On the 2nd and 3rd, I took Yuzhenteng, and from the 5th, I started taking Marvelon. However, my period has still not arrived. I would like to ask if there is a possibility of pregnancy.
Should I use a test strip to check for effectiveness?
Thank you.
Doctor's answer:
The test strips showed positive. However, it is common to experience menstrual irregularities after taking birth control pills. Based on your description, pregnancy is unlikely. Please adopt a satisfactory answer promptly and do not disappoint the responder.
