When it comes to the question of whether you need emergency contraception while on birth control, it's important to understand how both regular contraceptive methods and emergency contraception work, especially in the context of your specific situation involving polycystic ovary syndrome (PCOS) and the use of a hormonal contraceptive like the pill.

First, let's clarify what emergency contraception (EC) is. EC is designed to prevent pregnancy after unprotected intercourse or contraceptive failure (like a broken condom). There are different types of emergency contraception, including hormonal pills (like Plan B or Ella) and the copper intrauterine device (IUD). These methods are most effective when taken as soon as possible after unprotected sex, ideally within 72 hours for hormonal pills and up to 5 days for the copper IUD.

Now, regarding your use of the combined oral contraceptive pill (in your case, the "Shivina" pill), it is generally effective at preventing pregnancy when taken correctly. If you have been taking your birth control pill consistently and as directed for the past two months, the likelihood of pregnancy from unprotected intercourse is significantly reduced. However, if you missed any doses or took the pill inconsistently, this could compromise its effectiveness, and you might consider using emergency contraception.

In terms of your specific question about whether taking emergency contraception would affect your regular birth control pill, the answer is generally no. Emergency contraceptive pills do not interfere with the effectiveness of your ongoing hormonal contraceptive method. However, it is important to note that taking EC can cause some hormonal fluctuations, which might lead to changes in your menstrual cycle, such as earlier or later periods, or changes in flow.
If you are considering taking emergency contraception, it is advisable to consult with your healthcare provider. They can provide personalized advice based on your medical history, current medications, and the specifics of your situation. They can also help you understand how to manage your PCOS in conjunction with your contraceptive methods.

In summary, if you have been taking your birth control pill consistently, you may not need emergency contraception. However, if there is any doubt about your pill adherence or if you are concerned about the risk of pregnancy, taking emergency contraception is a reasonable option. Always consult with your healthcare provider for the best course of action tailored to your individual health needs.
