Use of contraceptive pills after ovulatory bleeding?


I have been using a contraceptive pill and stopped taking it for one month in January after using it for a year.
My last menstrual period was from December 27 to January 2, and my ovulation was expected around January 10.
I had sexual intercourse during that time, and I experienced some light brown spotting from January 12 to 14, which was minimal and only noticeable when I wiped.
Today, January 24, I should have started my menstrual period, but I had very light brown discharge for the past two days, and today there is none at all.

Could you please clarify if the brown discharge from the past two days is considered my menstrual period? Could the presence of ovulation bleeding in between cause a lighter menstrual flow? If I want to continue taking the contraceptive pill, can I start taking it now, or should I wait until my actual menstrual period begins?

Hello, it could be ovulatory bleeding.
If no contraception was used, pregnancy is also a possibility.
Wait a bit longer; if you don't get your period in another week, it's advisable to see a gynecologist.
If your period does come, start taking the contraceptive pill on the fifth day.
Wishing you good health.

More Info


Ovulation bleeding, often referred to as mid-cycle spotting, can be a perplexing experience for many women, especially those who are monitoring their menstrual cycles closely. In your case, the timeline you provided indicates that you had a menstrual period from December 27 to January 2, with your expected ovulation around January 10. The occurrence of light brown spotting between January 12 and 14 could indeed be attributed to ovulation bleeding, which is typically characterized by light spotting that occurs around the time of ovulation due to hormonal fluctuations.

During ovulation, there is a surge in estrogen levels, which can lead to a temporary thickening of the uterine lining. When ovulation occurs, the follicle releases an egg, and this hormonal shift can sometimes cause a small amount of the uterine lining to shed, resulting in light spotting. This is generally harmless and is not a cause for concern. The spotting you experienced, being light and brown, aligns with this phenomenon.

As for your question regarding whether this spotting could affect your menstrual period, it is possible. Some women may experience lighter periods following ovulation bleeding, as the hormonal changes can influence the thickness of the uterine lining. If the lining is thinner due to the shedding during ovulation, it may result in a lighter menstrual flow when your period arrives.

Regarding the use of contraceptive pills, it is essential to follow the instructions provided by your healthcare provider. Generally, if you are using a combined oral contraceptive pill, it is recommended to start taking the pills at the beginning of your menstrual cycle. However, if you are experiencing irregularities in your cycle, such as the light brown spotting you mentioned, it is advisable to wait until you have a more definitive menstrual period before starting the pill again. This ensures that you are not inadvertently disrupting your cycle further.

If you decide to resume taking the contraceptive pill, it is crucial to consider the timing. Starting the pill during a period can help regulate your cycle and provide effective contraception. If you are unsure about when to start or have concerns about your cycle, it is always best to consult with your healthcare provider. They can provide personalized advice based on your medical history and current situation.

In summary, the light brown spotting you experienced is likely ovulation bleeding, which is a common occurrence and usually not a cause for concern. It can potentially influence the flow of your subsequent menstrual period. When it comes to resuming contraceptive pills, it is advisable to wait for a clear menstrual period or consult with your healthcare provider for tailored guidance. Regular monitoring of your cycle and any unusual symptoms will help you maintain your reproductive health effectively.
