Patient's Query

Hello doctor,

I am a 18-year-old female with no known allergies, no history of pregnancy, and overall good health. Between the end of March and the beginning of April, which spanned approximately two weeks, I took three Plan B pills. I took the first one five days after a potential risk, the second three days later, and the third one the day after. I have taken a total of twenty pregnancy tests, all of which have consistently shown negative results. My last menstrual period was one week after my last Plan B pill.

I am concerned about the absence of my period and would like to understand what might be causing this delay. I am also wondering if my stress and anxiety about my period could be contributing to the situation. I have not experienced any pregnancy symptoms. If by any chance I were pregnant, I should be in my third month by now, which I believe is highly unlikely.

I am seeking your advice on what steps to take next and if there is any need for concern. I am struggling with ongoing stress and anxiety over this issue. Please help.

Thank you.


Welcome to icliniq.com.

Taking pills like Plan B (Levonorgestrel) can indeed disrupt your menstrual cycle as they contain progesterone, which can delay your period. Pregnancy tests typically yield accurate results after about three weeks from the date of sexual contact. I strongly advise against continued use of such pills, as excessive use can lead to complications in the future. Instead, consider other reliable methods of contraception such as condoms or diaphragms. You should expect your period to arrive within a week.

Thank you.
