Exact Conception Date

[JonOfLondon]

My girlfriend is pregnant with our second child, however, she's apparently been given an exact conception date (i.e. right down to the day). I hadn't realised that was possible. How accurate is this?

ive had 2 kids and never heard of an exact conception date as i just dont think its possible and cant see why anyone would need to know the date. generally you get a due date from working out the day the last period started so say the last period started on say 21st june by the 21st july if a pregnancy test was positive your girlfriend would therefore be 4wks pregnant in medical world. even a scan cannot give an exact date as they go on the size and measurements of the baby but scan date is generally more accurate than just working it out. the only way you can really tellt he exact date of conception is to only have sex on one day in the month until pregnant!

would there be any reason why your girlfriend would think its neccessary to know exactly when the baby was concieved?

women are normally most fertile for pregnancy 2wks after their period finishes.

even if she only had sex one day in that cycle itd be pretty difficult to work out if conception was immediate or 2 days later.

hiya, this isnt actually possible, unless you only had sex the one time and remember the exact date of it!

they work it out by your last period, say that was 28th june ( for example)
obviously everyone is different but its approximatly 2 weeks after that you start to ovulate, you ovulate for only appox 1-3 days
so...

if your last period was the 28th june you add on 2 weeks that makes 12th july so the next few days after this are the most likely to be day of conception

hope that helps, i aint that great at explaining things!! lol x

Interestingly enough, we went for our 'Three Month-ish' scan yesterday, and they 'measured' the baby on the computer attached to the ultrasound scanner, and told us that the baby was 13 weeks and 5 days.
