Delayed menstruation?
Taking emergency contraceptive pills for two consecutive weeks can disrupt your menstrual cycle.
You mentioned that your last period started on the 18th and ended on the 23rd of last month, and you took the emergency contraceptive pill on the 29th after unprotected intercourse on the 28th.
You took another emergency contraceptive pill on the 7th of this month after unprotected intercourse on the 4th, which resulted in some bleeding that lasted until the 7th, but then stopped on the 8th.
You noted that your period should have arrived by now, but you experienced some light pink discharge for two days recently.
Your menstrual cycle can sometimes be irregular, varying by a day or two.
As of August 20th, you still had not noticed your period, and you have been feeling emotionally low, experiencing irritability, palpitations, abdominal pain, and difficulty sleeping, often falling into a deep sleep.
You also mentioned a weight loss of one kilogram.
You took a pregnancy test on the morning of August 25th and again on August 31st, both showing only one line, indicating a negative result.
As of today, September 1st, your period has not arrived.
Regarding the likelihood of pregnancy after having unprotected intercourse on September 1st, the risk is present, especially since you did not use protection and did not ejaculate inside.
However, the use of emergency contraception may reduce the risk of pregnancy.
It is advisable to consult a healthcare professional for further evaluation and guidance.

Hello, the questioner: Due to the irregularity of your menstrual cycle recently, your ovulation period may not necessarily occur earlier or on time this time.
The effects of emergency contraception on menstruation can also vary, and repeated use may lead to even more irregular cycles.
Additionally, its contraceptive effectiveness is not 100%.
It is recommended that you consult a physician to check for any potential pregnancy and to determine if menstrual regulation is needed.
Based on your description, it would be better to use regular contraceptive pills, as they can provide both contraception and menstrual regulation, to avoid complications from contraceptive failure.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info
Understanding menstrual irregularities after the use of emergency contraceptives can be complex, as various factors can influence the menstrual cycle. Emergency contraceptive pills (ECPs), such as those containing levonorgestrel or ulipristal acetate, are designed to prevent pregnancy after unprotected intercourse. However, they can also cause temporary changes in your menstrual cycle.
When you take ECPs, they can lead to hormonal fluctuations that may result in irregular bleeding or changes in the timing of your next period. This is particularly true if you take the pills multiple times within a short period, as you mentioned taking them two weeks apart. The hormones in these pills can disrupt your normal ovulatory cycle, leading to unexpected bleeding or delays in menstruation.
In your case, you experienced bleeding after taking the ECP, which could be a side effect of the medication. The pink discharge you observed could also be related to hormonal changes rather than your regular menstrual flow. It’s not uncommon for women to experience lighter or irregular periods after using emergency contraception.
Regarding your concerns about pregnancy, the likelihood of becoming pregnant after unprotected intercourse depends on several factors, including the timing of your ovulation and the effectiveness of the emergency contraceptive taken previously. Since you took ECPs after unprotected sex, the chances of pregnancy are significantly reduced, but not eliminated. The fact that you have taken pregnancy tests that returned negative results is reassuring, but it’s important to note that testing too early can sometimes yield false negatives.
Your emotional state and physical symptoms, such as abdominal pain, mood swings, and sleep disturbances, may also be influenced by hormonal changes due to the ECPs or stress from your current situation. Stress can significantly affect your menstrual cycle, leading to delays or irregularities.
To summarize, the irregularities you are experiencing could be attributed to the use of emergency contraceptives, which can disrupt your hormonal balance and menstrual cycle. If your period does not arrive within a week or two, or if you continue to experience unusual symptoms, it would be advisable to consult a healthcare provider. They can offer guidance, perform further evaluations, and help determine if additional testing or treatment is necessary.
In terms of the risk of pregnancy from the unprotected intercourse on September 1st, while the chances are lower due to the previous use of ECPs, it is still possible. If you are concerned about pregnancy, consider using a reliable form of contraception moving forward and consult with a healthcare professional for personalized advice.
