###Human: I am on medication for PCOD. Do I need to take I-pill after unprotected sex? ###Assistant: Hello. As you are a known case of polycystic ovary syndrome (PCOS) there are chances that you may have delayed ovulation ad hence delayed menses. So, you must take an emergency contraceptive pill within 72 hours of last intercourse. Again you are on homeopathic medication which would have its effect for long-term and will not offer you any immediate protection.After the I-pill you should expect your menses in the next 7 days. If it does not occur, then you should rule out pregnancy with a serum beta-hCG test. Besides oral contraceptive pills (OCP) the best contraception for you would be a depot injection or a Norplant (Levonorgestrel) hormonal contraceptive. But, as you are a case of PCOS, hormones should be avoided and condoms should be used as barrier contraceptives.
