Post-Intercourse Discomfort and Menstrual Cycle Concerns Explained

Experiencing discomfort after eating and issues with the menstrual cycle?

Hello Doctor: My last menstrual period started on May 13, and my cycle averages between 27 to 32 days.
I had intercourse with my boyfriend on June 5, and the condom broke, but there was no ejaculation.
The next day, June 6, I took emergency contraception.
I have two questions: 1.
Since taking the emergency contraception, I have been experiencing stomach discomfort and nausea until today, June 8.
Should I seek medical attention? 2.
My period is expected to start on June 10.
Given that I took emergency contraception, how many days after should I expect my period? If it is delayed, how many days should I wait before seeking medical attention? Thank you, Doctor.

Hello, based on your description, if the symptoms persist or worsen, you should seek medical attention.
The effects of emergency contraception on menstruation can vary; it may not necessarily cause your period to come early or late.
Additionally, its contraceptive effectiveness is not 100%, with a failure rate of about 3%.
It is advisable to check for pregnancy if your period is more than a week late.
Thank you! Wishing you safety and health.

Hello! Thank you for your questions regarding post-intercourse discomfort and menstrual cycle concerns. Let's break down your concerns into two parts: the gastrointestinal symptoms you're experiencing after taking emergency contraception and the expected changes to your menstrual cycle.

1. Gastrointestinal Symptoms After Emergency Contraception: It's not uncommon to experience side effects after taking emergency contraceptive pills (ECPs), such as nausea, vomiting, and abdominal discomfort. These symptoms can occur due to the hormonal changes induced by the medication. If you are experiencing persistent nausea or vomiting, it is advisable to consult a healthcare provider. They can assess your symptoms and determine if further evaluation or treatment is necessary. In some cases, these symptoms may resolve on their own, but if they worsen or are accompanied by severe pain, it is important to seek medical attention.

2. Menstrual Cycle Changes After Taking Emergency Contraception: Emergency contraception can affect your menstrual cycle. Since you mentioned that your menstrual cycle typically ranges from 27 to 32 days, the timing of your next period may be influenced by the ECP. After taking emergency contraception, your period may come earlier or later than expected. Generally, if you took the pill on June 6, you can expect your period to arrive within a week or so of your expected date, which is around June 10. However, it is not unusual for the period to be delayed by a few days or even up to a week or more.

If your period is delayed beyond a week from the expected date, it would be wise to take a home pregnancy test to rule out pregnancy, especially since the condom broke during intercourse. If the test is positive or if you continue to experience unusual symptoms, you should consult a healthcare provider for further evaluation.

In summary, while gastrointestinal discomfort can be a common side effect of emergency contraception, persistent or severe symptoms warrant medical attention. As for your menstrual cycle, keep track of any changes, and if your period is significantly delayed, consider taking a pregnancy test and consulting a healthcare professional for guidance. Remember, it’s always better to err on the side of caution when it comes to your health. Take care!
