Emergency Contraceptive Pills: What to Do When Your Period Is Late?

I took emergency contraception, but I tested positive for pregnancy and my period still hasn't arrived?

The last menstrual period was from May 17 to May 21, with a stable cycle of 28-29 days (recorded on a mobile app for over a year).
After unprotected intercourse on May 26 and May 28, I took emergency contraception late on May 28, and vomited around early May 29.
After unprotected intercourse on June 1 and June 2, I took emergency contraception at noon on June 3 and vomited within three hours.
On June 12 and June 13, there was more unprotected intercourse, and I expected my period on June 14, but it did not arrive.
I took a pregnancy test on June 16, which showed negative, and I had unprotected intercourse that day as well.
On June 20 and June 22, there was more unprotected intercourse.
Today, June 23, I am experiencing nausea, dizziness, and persistent vomiting despite eating light foods.
My period still has not arrived, and I have also experienced lower abdominal pain similar to menstrual cramps and breast tenderness.
The situation is quite complicated.
What should I do? Is it still possible to take medication for the unprotected intercourse on June 22?

More Info

When dealing with a late period, especially after having unprotected intercourse, it's essential to understand the implications of emergency contraceptive pills (ECPs) and the potential reasons for menstrual irregularities. Based on your situation, let's break down the key points and provide guidance.

Understanding Your Cycle and Late Period
You mentioned that your menstrual cycle is typically stable, ranging from 28 to 29 days. Your last period was from May 17 to May 21, and you expected your next period around June 14. Given that you have had unprotected intercourse on multiple occasions and have taken emergency contraceptive pills, it's crucial to consider how these factors interact.

1. Emergency Contraceptive Pills (ECPs): ECPs, such as Plan B or Ella, are designed to prevent pregnancy after unprotected intercourse. They are most effective when taken as soon as possible after the incident, ideally within 72 hours for Plan B and up to 120 hours for Ella. However, they can cause temporary disruptions in your menstrual cycle, leading to a late period. Symptoms like nausea and breast tenderness can also be side effects of these pills.

2. Pregnancy Testing: You mentioned that you took a pregnancy test on June 16, which showed negative results. If you took the test after your expected period date and it was negative, it is a good indication that you are not pregnant. However, if your period does not arrive soon, you may want to retest a few days later, as hormone levels can take time to rise to detectable levels.

3. Symptoms of Nausea and Abdominal Pain: The symptoms you are experiencing, such as nausea, dizziness, and abdominal pain, could be attributed to hormonal changes from the ECPs or other factors like stress or changes in your routine. If these symptoms persist or worsen, it would be wise to consult a healthcare provider.

What to Do Next
1. Wait for Your Period: Since your cycle is typically regular, it may just be a matter of time before your period arrives. ECPs can delay your period by a few days to a week.

2. Monitor Symptoms: Keep track of any additional symptoms you experience. If you notice severe pain, heavy bleeding, or other concerning symptoms, seek medical attention promptly.

3. Consult a Healthcare Provider: If your period does not arrive within a week of your expected date, or if you continue to experience significant discomfort, it's advisable to consult a healthcare provider. They can perform a more sensitive pregnancy test and evaluate your symptoms.

4. Consider Future Contraceptive Options: If you find yourself in a situation where you are frequently concerned about unprotected intercourse, it may be beneficial to discuss long-term contraceptive options with your healthcare provider. This could include hormonal birth control methods, IUDs, or other reliable forms of contraception.

Conclusion
In summary, while your late period can be concerning, it is not uncommon after taking emergency contraceptive pills. Monitor your symptoms, consider retesting for pregnancy if your period does not arrive soon, and consult a healthcare provider if you have ongoing concerns. It's essential to prioritize your health and well-being, and a healthcare professional can provide personalized advice based on your specific situation.
