Emergency Contraception: What to Do If Your Period Is Late?

Emergency contraceptive pill

I would like to ask about a situation where my boyfriend accidentally ejaculated inside me after we had intercourse on March 9.
I took emergency contraception on the night of the 10th, and then I took another dose the following day.
However, as of now, March 21, my period has not arrived.
I have been taking pregnancy tests weekly, and all have come back negative.
I have noticed an increase in discharge, which is slightly more viscous.
What should I do?

When dealing with a late period after unprotected intercourse, especially following the use of emergency contraception (EC), it’s important to understand the implications and next steps. Based on your situation, where you had unprotected sex on March 9 and took emergency contraception on March 10, it’s crucial to note that EC is designed to prevent pregnancy but is not 100% effective.
Emergency contraception works primarily by delaying ovulation. If ovulation has already occurred, EC may not be effective. The timing of your menstrual cycle plays a significant role in this. If your cycle is typically regular, a late period can be concerning, but it can also be influenced by various factors, including stress, hormonal fluctuations, or the effects of the emergency contraceptive itself.

Given that you have been testing for pregnancy weekly and receiving negative results, it is a good sign that you may not be pregnant. However, it’s not uncommon for the hormonal changes caused by emergency contraception to delay your period. Some women may experience a delay of a few days to a couple of weeks after taking EC.
Here are some steps you can take moving forward:
1. Continue Monitoring: Keep monitoring your body for any signs of menstruation. If your period does not arrive within a week or two, consider taking another pregnancy test for confirmation.

2. Consult a Healthcare Provider: If your period remains absent for more than a week after your expected date, or if you experience any unusual symptoms (such as severe pain, heavy bleeding, or other concerning signs), it’s advisable to consult a healthcare provider. They can perform a more sensitive pregnancy test and evaluate your situation further.

3. Consider Other Factors: Reflect on any recent lifestyle changes that may have affected your cycle, such as stress, changes in weight, exercise habits, or illness. These factors can significantly impact menstrual regularity.

4. Understand the Effects of EC: Remember that emergency contraception can cause temporary hormonal changes, which may lead to irregularities in your menstrual cycle. This is a common side effect and usually resolves itself.

5. Future Contraceptive Planning: If you find yourself in a similar situation in the future, consider discussing regular contraceptive options with your healthcare provider. This can help prevent the anxiety associated with unprotected intercourse and the need for emergency contraception.

In summary, while it’s understandable to be concerned about a late period after taking emergency contraception, it’s essential to remain calm and monitor your situation. If your period does not arrive soon, or if you have any concerns, seeking medical advice is the best course of action. Your health and peace of mind are paramount, and a healthcare provider can offer the most personalized guidance.
