<s>[INST] Hi Doctor, We are married and have 2 children. My wife does not like me using condoms. Till date we practice natural contraceptive method using the cycle date, not having sex between 11th and 17 date of the cycle. Now my wife like to use a pill not regularly but just before having sex - may be one before or after having sex, in order to prevent pregnancy. Are there any pills available? [/INST] Hello dairy understand your concerned can use I pill hour after the sex to prevent the pregnancy. But it should be used for only emergency purpose. Regular use can cause menstrual irregularity and lots of side effect. Better to use birth control pill. But it should be used regularly on every day to prevent the pregnancy. Your wife can also use vaginal diaphragm, demo shot and IUD like copper T. So consult the gynecologist and choose the best contraception for you. Hope this may help noncontact Chat Doctor for further health query Best regards </s>
