Emergency contraception (EC) is a crucial topic for individuals who are sexually active and want to prevent unintended pregnancies. Based on your situation, let's break down your questions and concerns regarding the use of emergency contraception, its effectiveness, and what to expect afterward.

1. Timing and Effectiveness of Emergency Contraception: You mentioned that you had unprotected intercourse on May 4th, which falls within your fertile window, as you identified May 6th as your ovulation day. The effectiveness of emergency contraception, particularly the pill, is highest when taken as soon as possible after unprotected intercourse. Since you took the first dose on May 5th and the second dose on May 6th, you acted promptly, which maximizes the chances of preventing ovulation and thus reduces the risk of pregnancy. Generally, emergency contraceptive pills can be up to 89% effective when taken within 72 hours after unprotected sex, but their effectiveness decreases the longer you wait.

2. Subsequent Intercourse After Taking EC: After taking the emergency contraception, you had another instance of unprotected intercourse on May 6th. Since you had already taken the emergency contraceptive pills, it is advisable to take another dose if you have unprotected sex after taking the EC. This is because the pills work primarily by preventing ovulation; if you ovulate after taking the first dose, subsequent intercourse could lead to pregnancy. Therefore, in this case, it would be wise to take another dose of emergency contraception.

3. Spotting After Taking EC: It is common to experience some irregular bleeding or spotting after taking emergency contraception. This bleeding is not considered a true menstrual period but rather a side effect of the hormonal changes induced by the medication. It does not necessarily indicate that you are or are not pregnant. The occurrence of spotting can happen within a few days after taking the pills and is generally not a cause for concern. However, if you experience heavy bleeding or other unusual symptoms, it is advisable to consult a healthcare provider.

4. Determining Pregnancy: The only way to confirm whether you are pregnant after taking emergency contraception is to take a pregnancy test. It is recommended to wait at least one week after your expected period to take a home pregnancy test for the most accurate results. If your period is late or you have other symptoms of pregnancy, such as nausea or breast tenderness, a pregnancy test will provide clarity.

5. Understanding Your Cycle: Your menstrual cycle can be affected by various factors, including stress, hormonal changes, and the use of emergency contraception. If you notice significant changes in your cycle or have concerns about your reproductive health, it may be beneficial to speak with a healthcare professional who can provide personalized advice and support.

In summary, based on your timeline and actions, you have taken appropriate steps to prevent pregnancy after unprotected intercourse. If you have further questions or concerns, especially regarding the need for additional doses of emergency contraception or the implications of any bleeding, do not hesitate to reach out to a healthcare provider. They can offer guidance tailored to your specific situation and help you navigate any uncertainties regarding your reproductive health.
