I have been taking femilon since 20days and this is the first time I have been taking femilon . I have irregular periods so my doctor suggested me to take femilon as I was having heavy bleeding . I started femilon on 13th of march 2013 and now only 1 pill is left I have been taking femilon withou missing any pills but not at the same time everyday. I had unprotected sex with ejaculation inside my vagina on the second last day of my pill after intercourse I took my second last pill. Can you please tell me what are the chances of me being pregnant I am still left with 1 last pill of femilon to complete the 21 pack.
