[|Human|] I had unprotected sex and i took next choice first pill 24 hours of having unproted sex. But i forgot to take the second pill after 12 hours of taking the first pill. so i took the secong pill 20 hours.Please i want to know if it will still be effective in preventing pregnancy
[|AI|]  Hi, The earlier after sex you take next choice, more effective it is.  Next choice if taken within 24 hours is 95% effective. Ideally as you know the second dose should be taken after 12 hours. If taken later, its efficacy may decrease. Therefore, if your period is delayed by more than 7 days, get a pregnancy test done. To avoid such unnecessary stress I advise you to consult your doctor and start regular contraception like hormonal contraception or have an intrauterine device fitted as they are more effective than Posting in preventing pregnancy. It is wise to use barrier contraception like Condom to protect yourself from sexually transmitted diseases. I hope I have answered to your satisfaction.
