Menstrual Changes After Taking Emergency Contraception

Menstruation after emergency contraception?

Her last menstrual period started on the 12th.
On November 27th, we helped each other with masturbation without direct penetration, but I accidentally got semen on my hand and then inserted my finger.
On the morning of the 29th, I took the emergency contraceptive pill ELLA, but I'm still worried.
How can I confirm whether I might be pregnant? How should I track my menstrual cycle? If my period comes, does that mean I'm not pregnant, or when should I take a pregnancy test?

Hello, a pregnancy test should be taken at least 12 days after conception for accurate results.
The chances of pregnancy are low, so it is advisable to use contraception beforehand.
If your period is more than a week late, it is recommended to see a gynecologist.
Wishing you good health.

More Info

When it comes to understanding menstrual changes after taking emergency contraception like ELLA (ulipristal acetate), it's essential to recognize how this medication works and its potential effects on your menstrual cycle. ELLA is designed to prevent pregnancy after unprotected intercourse or contraceptive failure, and it is most effective when taken as soon as possible after the event.

How ELLA Works
ELLAs active ingredient, ulipristal acetate, works primarily by delaying or inhibiting ovulation. If ovulation has already occurred, it may also alter the endometrium (the lining of the uterus) to prevent implantation of a fertilized egg. However, it does not terminate an existing pregnancy.

Menstrual Changes After Taking ELLA
After taking ELLA, some women may experience changes in their menstrual cycle. These changes can include:
1. Timing of Menstruation: Your next period may come earlier or later than expected. It is common for the menstrual cycle to be disrupted after taking emergency contraception. If your cycle is typically regular, a delay of a week or more may occur.

2. Flow Changes: The flow of your period may be lighter or heavier than usual. Some women report spotting or breakthrough bleeding after taking ELLA.

3. Symptoms: You may experience symptoms such as breast tenderness, nausea, or mood changes, which can also be associated with hormonal fluctuations.

Confirming Pregnancy
To determine whether you are pregnant after taking ELLA, you should consider the following:
1. Wait for Your Period: If your period arrives within a week or two of when it was expected, it is a good sign that you are not pregnant. However, if your period is more than a week late, it is advisable to take a pregnancy test.

2. Timing of the Pregnancy Test: For the most accurate results, it is best to take a home pregnancy test at least one week after your missed period. This allows enough time for the hormone hCG (human chorionic gonadotropin), which is produced during pregnancy, to build up to detectable levels in your urine.

3. Follow-Up: If you have concerns about your menstrual changes or if you experience unusual symptoms (such as severe abdominal pain or heavy bleeding), it is important to consult a healthcare provider for further evaluation.

Conclusion
In summary, after taking ELLA, it is normal to experience some changes in your menstrual cycle, including timing and flow. If your period comes, it generally indicates that you are not pregnant. However, if your period is significantly delayed, taking a pregnancy test is recommended. Always consult with a healthcare professional if you have any concerns or questions regarding your reproductive health or the effects of emergency contraception.
