Conception Date

[ZoeUnsure]

Hi,
Im new to this forum and was hoping someone could help.
Today (05.09.2014) I had a scan and found out I was 7 weeks 6 Days pregnant and my due date was 18th April 2014.
I have been using online calculators to try and work out the conception date and they have all said around 24th July - 1st August, but have put my expected last period around the 10th July which isn't correct, the first day of my last period was 20th June and it lasted around 4/5 days.
Does anyone know what my conception date actually would be? would it changed if my last period was earlier than the calculator thought? or would it still be around then because of my due date?
Hopefully someone could help clear this up for me, thanks

okay, so how long before that would i have had intercourse? Could it of been as early as 3 weeks before conception date?xx

Sperm lives between 5-7 days in a females body.
So 5-7 days before you ovulated.

I don't know when I ovulated? There is like 40 days between my last period and my estimated conception date?
