hi if like my wife you keep a little book that tracks your period dates you just have to work it from that if your cycles are normal so its your one in may + 14 days to ovulation day so if you had unprotected sex 3 to 4 days before that then bingo you have found the day or days your looking for. ok its from that period date you work your 9 months from. ok good luck
okay so my dr and ultrasound tech says i'm 9w5d and my due date is 2/19/17 and i'm trying to understand the conception. my husband and i were together on the 26th and the 28th and 29th and every calculator i look at says conception date of 29th. and i even counted from the due date back 266 days.
