When it comes to understanding the risks associated with contraceptive pills and unprotected intercourse, it's essential to consider several factors, including the effectiveness of the contraceptive method, the timing of intercourse in relation to your menstrual cycle, and the specifics of your situation.

Firstly, if you have been consistently taking your contraceptive pill (also known as the birth control pill) for over a year, and you take it at the same time every day, the effectiveness of the pill is very high—typically around 99% with perfect use. This means that the likelihood of becoming pregnant while on the pill is quite low, even if you have unprotected intercourse. However, it is crucial to remember that no contraceptive method is 100% effective.

In your case, you mentioned that your boyfriend had unprotected intercourse on September 5th, and you are unsure if he ejaculated inside you. If you have been taking your pill correctly, the chances of pregnancy from this encounter are minimal. The pill works primarily by preventing ovulation, so if you are not ovulating, there is no egg available for sperm to fertilize, which significantly reduces the risk of pregnancy.

However, there are a few considerations to keep in mind:
1. Timing in Your Cycle: If you are taking the pill correctly, the timing of intercourse in relation to your menstrual cycle is less of a concern. The pill suppresses ovulation, but if you miss a pill or take it late, it could potentially lead to ovulation, increasing the risk of pregnancy.

2. Missed Pills: If you have missed any doses of your contraceptive pill or taken them inconsistently, this could affect its effectiveness. If you missed a pill, especially in the week before your unprotected intercourse, you should consult the instructions provided with your medication or speak with your healthcare provider for guidance.

3. Emergency Contraception: If you are still concerned about the possibility of pregnancy, you may consider taking emergency contraception (often referred to as the "morning-after pill"). This is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but some types can be effective up to 5 days after.

4. Pregnancy Testing: If your period is late or you experience any unusual symptoms, it would be wise to take a home pregnancy test or consult with your healthcare provider for further evaluation.

5. Regular Check-ups: It’s also a good idea to have regular check-ups with your healthcare provider to discuss your contraceptive method and any concerns you may have. They can provide personalized advice based on your health history and lifestyle.

In summary, if you have been diligent about taking your contraceptive pill, the risk of pregnancy from the described encounter is low. However, if you have any doubts or missed pills, consider taking emergency contraception and consult with your healthcare provider for further reassurance and guidance. Remember, open communication with your partner about contraceptive use and sexual health is also essential for peace of mind.
