My period ended on November 14th.

More Info
Understanding your menstrual cycle can be quite complex, especially when factors such as hormonal medications and sexual activity come into play. Based on the information you've provided, let's break down your situation.
Your last menstrual period (LMP) started on November 9, and you took a hormonal medication (Nina) to regulate your cycle, which ended on November 14. After that, you engaged in protected sexual intercourse on November 24, 25, and 26. You completed your course of hormonal medication on December 3, and as of December 7, you are on day 29 of your cycle without the onset of menstruation.
Typically, a menstrual cycle ranges from 21 to 35 days, with the average being around 28 days. However, cycles can vary significantly from person to person and even from month to month. Factors such as stress, changes in weight, exercise, and hormonal medications can all influence the timing of your period.
Since you have recently taken hormonal medication, it is essential to consider how it may affect your cycle. Hormonal contraceptives can sometimes lead to a delay in menstruation, especially if your body is adjusting to the medication. It is not uncommon for periods to be irregular or delayed after starting or stopping hormonal treatments.
Given that today is December 7 and you are on day 29 of your cycle, your period could still arrive within the next few days. Many women experience variations in their cycle length, and it is possible that your period may be delayed due to the hormonal medication you took. If you do not experience menstruation within a week or so, it may be advisable to take a home pregnancy test, especially since you had unprotected sexual intercourse during your fertile window.
If your period does not arrive and you have concerns about potential pregnancy or other health issues, it is essential to consult with your healthcare provider. They can provide personalized advice and may recommend further evaluation or testing to understand your menstrual health better.
In summary, while it is difficult to predict the exact timing of your next period, it is essential to monitor your body and any changes you experience. If your period does not arrive soon, consider taking a pregnancy test and consulting with your doctor for further guidance. Remember that menstrual health can be influenced by various factors, and maintaining open communication with your healthcare provider is crucial for managing your reproductive health effectively.
