These pills have to be taken within 72 hours, the sooner, the better. Emergency contraceptive pills only protect against pregnancy when taken after sex. That means a woman can still get pregnant if she takes emergency contraception and then have sex again without using another kind of contraception. BUT remember these are supposed to be taken in emergencies only. Do not use them for everyday use or when you being careless with protection. These pills affect the menstrual cycle of a woman. So PLEASE don't misuse these pills. You claim to love her, respect her and her body, also. From today onwards, please use a condom for both of yours sake. https://lovematters.in/en/resource/safe-sex If you would like to join in on a further discussion on this topic, join our discussion board, "Just Ask” https://lovematters.in/en/forum
