<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi i am using the contraceptive pill cerazette. I forgot to take it on sunday night the 17th march at half 10 an never took it until the following monday morning at half 11 after the 12 hours that monday night i had unprotected sex. I went and got the morning after pill ellaone on the friday morning 22nd march, 88hrs after the unprotected sex. The woman told me to do a pregnancy test 3 weeks after, iv taken one today the 3rd april and it appears negative. Is it too early to tell? Can cerazette affect the result and also can this pill give pregnancy like symptoms?ThanksHannah  <response>: Hi Hannah, Thank you for posting your question here, I will try to answer it to the best of my abilities. Usually youre supposed to take two pills in order to make up for the missed one, thats what Ive been told by most doctors. The smart thing you did was taking the emergency pill on the next day, ellaone can be taken up to 5 days after having unprotected sex, so since you were just over the 3rd day, it shouldve worked. Now what you need to know is that Elaine had been shown to stop 60 of all cases, so its not 100. But since youre home pregnancy test has come out negative after waiting for 3 weeks, it is highly unlikely that you are pregnant, to be 100 sure, you can take another home pregnancy test tomorrow. I hope this answered your question.
