Hello, I took 6 pills of the oral contraceptive Microgestin Fe 1/20 this morning as a form of emergency contraception. It is roughly 60 hours after unprotected sex. I plan on taking 6 more pills 12 hours later. This will be the fourth time that I have done this in 9 months, as I am in a foreign country where the Plan B pill is unavailable, and I frequently forget to take my oral contraceptives on a daily basis. In the past, side effects have been nausea and vomiting, but it has been effective in preventing pregnancy. However, since this is my fourth time doing this and since Microgestin is not intended for emergency contraception, I am extremely nervous about dangerous side effects. Please tell me what side effects are possible, how likely they are, if there is anything I should do immediately to prevent dangerous side effects, and if it is advisable to take the other 6 pills in 12 hours for this time only.
