### input:
I took Plan B emergency contraceptive on March 24 (Cycle Day 7) and again on March 26 (Cycle Day 9)... Copper T IUD came out on the 24th and we werent too careful.  My partner and I spoke about it after the fact and we decided that we are ready to become parents so taking this dreadful pill was more a mistake than the intercourse.  I bled on April 5th (lightly) until April 8th.  My boyfriend and I are now trying to conceive and I am wondering how these pills will affect my cycle (I am regular and my cycle varies from 27-30 days).  We have had intercourse daily since the 9th and today my period was due, but did not arrive.   My questions are: I took a pregnancy test about 10 minutes ago and the result is negative... is it possible I could have ovulated late and could be in the process of conceiving now --- or did plan B destroy my chances of conceiving this cycle?Was the April 5th bleed my period and should it be considered cycle day 1?  Or should i still expect a period?How will my ovulation be affected?  They say 14 days before your next period is your most fertile time... when should we be diligent in trying?

### output:

Hi, It is most likely that your cycle is disrupted this time and the chances of ovulation are poor owing to the use of the emergency pill. The bleeding you had was the breakthrough after the pills. You may receive your normal cycle either as expected or a little later. If you do not get a period 10-14 days within your expected date, you should consult your doctor for an assessment.  It is true that 14 days before the next cycle is the day of ovulation and is the most fertile time for conception. Hope this information is useful. Good luck.
