Hi, I guess your concern is about is about chances of getting pregnant after unprotected sex in spite of taking Devary. Firstly, my straight forward answer is YES. There is chances of getting pregnant. Because devary is given for the withdrawal bleeding (that means bleeding, which occurs after delayed menses), not for the purpose of emergency contraception and emergency contraception usually taken within 72 hours of unprotected sex. So I want to tell you not to worry as every problem have solutions. As you told that you have Polycystic ovary. It also causes delay in menses. With the above discussion, you can try out my suggestions: 1. First to do urinary pregnancy test by a kit, it is easily available in your nearby medical store and do it. If it is negative, then don t worry, menses will came with or without medication. But if it is positive then you can visit to nearby gynecologist, he/she can help you. 2. If you are still having irregular menses then your treating gynecologist also helps you. I hope the above things are informative enough, useful n helpful for you. Let em know if I can assist you further. Regards, Dr. Sudha Rani Panagar
