hello doctor, my gynec suggested me to use femilon as contraceptive. my age is 24 and weight is 49. recently i am having delays in periods, like 34/35 day cycle instead of 28/30 day that i had. until now we have used only condoms and this is the first time I will be taking pills.my question is, after completing the 21 day course, can I still continue to have unprotected sex with my partner until my next period starts... because if my cycle is ~34 days, post 21 pills is it safe to have unprotected sex? i am meeting my parner only on the 20th day of my cycle for a week. so out of my 7 days of intimacy with him, my pills will last only for first two days.looking forward for your valuable guidance. Thanks!
