Ok so you need to find out the day, but if you count exactly nine months back you should be able to narrow down the exact day. I would say sometime time in September/ early October. If you post the date, it would be easier for me to figure out. As you haven't provided an accurate date in June, it is estimated that she conceived around 9 September - 9 October.
It depends if you were five weeks pregnant or five weeks from conception. If five weeks pregnant you conceived around 18 May, if five weeks from conception you conceived around 4 May. If you could see a heartbeat you were 5 weeks from conception.
If you gave a due date it might be easier to calculate. Some calculate your due date according to your date your last period started and ended. I'm going to guess that the conception took place sometime around March 26th to April 2nd. But if you gave the due date it would be a little easier.

Erm ... 20 weeks and four days ago ... Dohh!! Look at a calendar and count backwards 20 weeks, then backwards 4 days - there is your estimated date of conception.
