When did we have s*x? to get pregnant?

Question

My girlfriend and i are expecting a baby, we went for a scan today to reveal she is 6 weeks pregnant.

Can anybody tell us, WHEN did we have s*x to get her pregnant? we are trying to figure this out as we don't know weather we had s*x to match up with the dates, so any info on how long it would take sperm or when do you actually be CLASSED as pregnant or ANY relevant information would be brilliant

Thank you

Answer 1

They count the date as the first day of her last period.  They estimate that the pregnancy actually occurs roughly two weeks later, depending on her cycle.  So while she is officially 6 weeks pregnant she is technically at 4 weeks physical gestation.  I know, it can be confusing.  So if she is six weeks now, count back 4 weeks on the calendar and you can get a general idea of when it happened.  It's not exact but a fairly good estimate.

The actual implantation can take anywhere from a few hours to a few days after s*x.  For instance when I was pregnant with my daughter(sorry if TMI), my hubby and I fooled around on Nov 6 (knew it for sure)and they gave me a conception date of Nov 9.  My due date was then calculated to be August 1 (40 weeks)

Answer 2

Well usually if your six weeks pregnant...

it takes about 1-2 weeks depending on her uterist!

So pro bally about 8 weeks ago!

Answer 3

If you have any concerns if they match up then you should really be asking if she has/had been with anyone else. I hate to burst your bubble but anything is possible.

Answer 4

When they say she's 6 weeks pregnant, they don't start counting from the date of conception for from the first day of her last period.

So if today the doctor says I'm 4 weeks pregnant for example, I know that technically the baby is only 2 weeks old as this is when we conceived it. 4 weeks ago, I was starting my period and my man was abroad. :)  

Answer 5

you can't rely on the ultrasound  to determine the true age of the baby, this much I can tell you. It can only tell you how your child is developing. My kids both measured a week older in the ultrasound than they actually were. Find out when your gf's last period was, and count from the last day of her period. it all depends on when she ovulates, nobody can say for sure without that. estimating my duedate was easy, as the last day of my period was the day I had conceived.

Answer 6

line up these three things:

when did your wife ovulate (aprox six weeks ago)

when did you have s*x.

betwen 5.5-6.5 weeks ago.

s***n cant be 'stored' inside a woman, as teh immune system attacks the sperms. so conception is bound to have taken place at the most a few hours after intercourse.

Answer 8

sounds to me like your real question is whether it is yours or not.

Answer 9

A scan does not reveal gestational length with any guarantee of accuracy. Use the first day of her last period and count forward 42 weeks to get an estimated due date for a first time mother. You would have conceived sometime after her period. It is not usually possible to find the exact day of conception as it occurs over a range of time. Congrats and best wishes, G

Answer 10
