Post-coital and pre-coital contraceptive pills can cause prolonged menstrual bleeding?
Hello,
I had a regular menstrual cycle of about 30-33 days.
My last period started on May 15, and I had safe sexual intercourse (using condoms).
On June 15, there was an accidental contraceptive failure.
Although I felt my period was approaching, I took the emergency contraceptive pill, Ella, just in case.
My period started on June 18, and I began taking the combined oral contraceptive pill (21 tablets) on the first day of my period.
The flow in the first few days was similar to my previous periods.
However, by the seventh day, while it seemed to be ending, I experienced continuous light spotting (including blood clots) that resembled the last day of my period, with only a small amount of blood.
It has been about a day’s worth of sanitary pad usage, and I have completed the entire pack of the contraceptive pill, yet I am still experiencing light spotting.
Aside from this, I have no other symptoms or discomfort.
What could be the reason for this? Will my period in July still occur? Should I see a doctor? (I used the same type of contraceptive pill last year without experiencing this issue.)

Hello, please finish taking the emergency contraceptive pill and start the next pack of birth control pills on the fifth day after your period begins.
Monitor for any abnormal bleeding; if it persists, it is advisable to consult a gynecologist.
Wishing you good health.

More Info
It seems you are experiencing some irregularities in your menstrual cycle after taking emergency contraception (Ella) and starting a new birth control pill regimen. Let’s break down your situation and provide some insights based on medical knowledge.
Firstly, it’s important to understand that hormonal contraceptives, including emergency contraception and regular birth control pills, can significantly affect your menstrual cycle. After taking Ella, which is a form of emergency contraception, it is common for your next period to be earlier or later than expected, and the flow may be lighter or heavier than usual. This is due to the high dose of hormones in emergency contraceptives that can disrupt your normal hormonal balance temporarily.
In your case, you mentioned that your period started on June 18 after taking Ella, and while it initially seemed normal, you are now experiencing prolonged light bleeding (spotting) that resembles the end of a typical menstrual period. This can happen for several reasons:
1. Hormonal Fluctuations: The hormones in both emergency contraception and the birth control pills can lead to irregular bleeding patterns. Spotting can occur as your body adjusts to the new hormonal levels, especially if you just started taking the birth control pills.
2. Breakthrough Bleeding: This is common when starting a new birth control method. It can happen in the first few months as your body adapts to the hormones. Breakthrough bleeding is usually lighter than a regular period and can last for a few days to weeks.
3. Incomplete Menstrual Cycle: Since you took emergency contraception, your body might not have had a chance to reset its cycle properly. This can lead to irregular bleeding patterns, including prolonged spotting.
Regarding your concern about whether your July period will still come, it is possible that your cycle may be disrupted due to the recent hormonal changes. However, many women still experience their next period even after irregularities. It’s essential to monitor your symptoms and menstrual flow. If you notice that the bleeding continues for an extended period, becomes heavier, or is accompanied by significant discomfort, it would be wise to consult a healthcare provider.
In terms of whether you need to see a doctor, if the spotting persists beyond a week or if you experience any other concerning symptoms (such as severe pain, heavy bleeding, or signs of infection), it would be advisable to seek medical attention. A healthcare professional can provide a thorough evaluation, possibly including an ultrasound or blood tests, to rule out any underlying issues.
Lastly, remember that while hormonal contraceptives are effective at preventing pregnancy, they are not 100% foolproof. If you have concerns about potential pregnancy, especially after a contraceptive failure, consider taking a pregnancy test if your next period does not arrive as expected.
In summary, irregular bleeding after starting hormonal contraception is common and often resolves on its own. However, keep track of your symptoms, and don’t hesitate to reach out to a healthcare provider if you have any concerns or if your symptoms change. Your health and peace of mind are important, and a doctor can provide the reassurance and guidance you need.
