took plan B/ an emergency contraceptive around June 24th 2008. I got my period about a week late being around July 3, 2008 which lasted until about July 7th, 2008. I had sex on either the 7th or 8th of July of 2008, then again on the 11th, 2008 and once more on around the 18th, 2008. My daughter was born on April 9, 2009. When would i have most likely conceived?
