Evening everyone. was just wondering, if i count 38 weeks back from my due date, will that tell me exaclty when our bubba was concieved? Before our scan, we were counting from the day of my last period (which is about 40 weeks) but now that the date has been brought forward by 2 days, i dont really understand when they are counting from as i dont thave my last period date wrong. Im just intrigued and would like to know exaclty which night was our lucky night as we did it quite a lot over this time!
