No one knows. So this makes 11-17 being most fertile days. Your eggs live for 2 days without being fertilized, and 5 to 7 days mans sperm live. If you release the egg as early as 3 days before 14--mans sperm could be inside you since the 7th if environment is favorable, and you could still get pregnant from that. If you release egg towards end of cycle which would be the 17th, you could get pregnant until the 19th day of the month.
