Hello, emergency contraceptive pills can sometimes cause irregular menstruation, but the chances of pregnancy should be low.
A pregnancy test should be taken at least 12 days after conception to yield accurate results.
It's best to use preventive measures beforehand.
If you continue to experience discomfort, it is recommended to see a gynecologist.
Wishing you good health.

More Info
Your concerns about pregnancy and irregular menstrual cycles are completely valid, and it's important to address them with accurate information. Let's break down your questions and provide some clarity.
1. Can the color and amount of menstrual blood indicate pregnancy?
The color and amount of menstrual blood can vary for many reasons, including hormonal fluctuations, stress, and changes in diet or lifestyle. In early pregnancy, some women experience light spotting or bleeding, often referred to as implantation bleeding, which can be brown or light pink. However, the presence of brown or red blood does not definitively indicate pregnancy. If you suspect you might be pregnant, the most reliable way to confirm this is through a home pregnancy test or a visit to your healthcare provider.
2. Can we determine if we are pregnant after two sexual encounters?
If you had unprotected sex during your fertile window (which is typically around ovulation), there is a possibility of pregnancy. However, if you used condoms and took emergency contraception (the morning-after pill), the chances of pregnancy are significantly reduced. Home pregnancy tests can typically detect pregnancy about a week after a missed period. If you take a test too early, it may not provide an accurate result. If you are still unsure, it’s best to consult with your healthcare provider for further testing.
3. Why is there variation in the color of menstrual blood?
The variation in color (brown, red) and flow (light, heavy) can be attributed to several factors. Brown blood often indicates older blood that has taken longer to exit the uterus, while bright red blood is usually fresher. Hormonal changes, stress, and even dietary factors can influence the menstrual cycle and the characteristics of menstrual blood. If you notice significant changes in your menstrual cycle or if the bleeding is accompanied by severe pain, it’s advisable to seek medical attention.
Additional Considerations:
- Emergency Contraception: Since you mentioned taking emergency contraception, it's important to note that this can cause changes in your menstrual cycle, including irregular bleeding or spotting. This is a common side effect and may not necessarily indicate pregnancy.
- Frequent Urination and Nausea: These symptoms can be associated with early pregnancy, but they can also be caused by anxiety, dietary changes, or other factors. If you are experiencing these symptoms consistently, it would be wise to take a pregnancy test or consult with a healthcare provider.
- Consulting a Healthcare Provider: Given your ongoing concerns and the complexity of your symptoms, it would be beneficial to schedule an appointment with a healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly blood tests, to provide you with a clearer understanding of your situation.
In summary, while the symptoms you are experiencing can be indicative of pregnancy, they can also result from other factors. The best course of action is to take a home pregnancy test after a missed period or consult with your healthcare provider for further evaluation. Your health and peace of mind are paramount, so don’t hesitate to seek professional guidance.
