When it comes to the question of whether you need emergency contraception after unprotected sex, it's essential to understand the timing of ovulation and the effectiveness of emergency contraceptive pills (ECPs). In your case, you mentioned having unprotected sex on the 14th and starting a regimen of SHITON S.C. TABLETS (which contains norethindrone) on the 17th.
Emergency contraception is most effective when taken as soon as possible after unprotected intercourse. The sooner you take it, the better the chances of preventing pregnancy. ECPs can be taken up to 72 hours (3 days) after unprotected sex, but some types can be effective up to 5 days after. However, their effectiveness decreases the longer you wait.
Given that you had unprotected sex on the 14th and began taking the contraceptive on the 17th, you would have missed the optimal window for ECPs. Therefore, it is advisable to take emergency contraception as soon as possible after unprotected sex to maximize its effectiveness.
Regarding your question about the timing of taking the SHITON S.C. TABLETS and whether you can skip emergency contraception if you have unprotected sex before starting the pills, it is crucial to note that these tablets are primarily designed for regulating menstrual cycles and may not provide immediate protection against pregnancy if taken after unprotected intercourse. If you have unprotected sex before starting the tablets, you should still consider taking emergency contraception to prevent an unintended pregnancy.

In summary, if you had unprotected sex on the 14th, you should have taken emergency contraception as soon as possible. Starting the SHITON S.C. TABLETS on the 17th does not negate the need for emergency contraception if you had unprotected sex just before that. If you are unsure about your risk of pregnancy or the effectiveness of your current contraceptive method, it is always best to consult with a healthcare provider for personalized advice and guidance.

In addition to the immediate concerns about pregnancy, it's also essential to consider sexually transmitted infections (STIs). Unprotected sex increases the risk of STIs, including HIV. If you have concerns about potential exposure to STIs, it is advisable to get tested and discuss preventive measures with your healthcare provider.

Lastly, if you are experiencing anxiety or stress related to your sexual health, seeking support from a healthcare professional can provide you with the necessary information and reassurance. They can help you navigate your options and make informed decisions about your sexual health moving forward.
