Menstrual flow is minimal to almost absent?

I have been taking birth control pills for over four years.
My last menstrual period was normal, but this time I forgot to buy new pills, so I mixed two types of previously missed pills.
I miscalculated the timing and stopped taking the pills a week before I was supposed to.
After three days without a period, I realized I had stopped a week early, so I resumed taking the pills until the scheduled stop.
This time, my period was two days late and appeared as brown spotting, with no menstrual flow at all.
Should I continue using the new birth control pills in five days? My last menstrual period started on July 27, and I have been sexually active.
Do I need to take a pregnancy test?

Therefore, I suggest you take a pregnancy test to check if you are pregnant.
If the result is negative, you can continue taking the pills next month.

Understanding abnormal menstrual changes after the use of birth control can be quite complex, especially when there are variations in how the medication is taken. In your case, it seems that there were several factors that could have contributed to the changes in your menstrual cycle.
Firstly, it’s important to recognize that hormonal contraceptives, such as birth control pills, work by regulating the hormones that control the menstrual cycle. When you take these pills consistently, they typically lead to a more predictable cycle. However, any deviation from the prescribed regimen—such as forgetting to take a pill, mixing different types of pills, or stopping the medication prematurely—can disrupt this hormonal balance and lead to irregularities in your menstrual cycle.

In your situation, you mentioned that you mixed two different types of birth control pills and also stopped taking them a week earlier than intended. This could have caused your body to respond unpredictably. The brown discharge you observed instead of a normal menstrual flow is often referred to as "spotting" and can occur for several reasons, including hormonal fluctuations, the effects of the birth control itself, or even the onset of a new menstrual cycle. Brown discharge typically indicates older blood that is taking longer to exit the body, which can happen when the uterine lining is shed more slowly than usual.

Given that you have had unprotected sexual intercourse and are experiencing a delay in your menstrual cycle, it is advisable to take a pregnancy test. The hormonal changes caused by inconsistent birth control use can lead to a false sense of security regarding pregnancy prevention. A home pregnancy test can provide clarity on whether or not you are pregnant, especially if your period does not arrive as expected.

As for whether you should continue taking the new pack of birth control pills, it is generally recommended to resume taking your pills as directed once you have confirmed that you are not pregnant. However, if you are uncertain about your pregnancy status or if your menstrual irregularities persist, it would be wise to consult with a healthcare provider. They can offer personalized advice based on your medical history and current situation.

In summary, hormonal contraceptives can lead to changes in menstrual cycles, especially when there are inconsistencies in how they are taken. The brown discharge you are experiencing could be a result of these changes. Given the circumstances, taking a pregnancy test is a prudent step, and consulting with a healthcare professional can provide you with the best guidance moving forward. Remember that maintaining a consistent schedule with your birth control is key to its effectiveness, and any changes should be discussed with a healthcare provider to ensure your reproductive health is managed appropriately.
