What does this mean??

[EB86]

Apologies if this isn't the correct place to ask this but, what does it mean when people say they're 10+5 weeks pregnant, or 4+2 weeks, for example?

Being naive and only just starting to try and conceive, I'd always just assumed you're pregnant from the date of conception but now I understand it's actually calculated from 1st day of last period.

So, is that where the 4+2 comes in...does it mean 4 weeks from conception + 2 weeks to count from last period??

And, if that's the case if you're 3 weeks since conception but 5 weeks since last period then are you classed as 3 weeks or 5 weeks pregnant?

I'm soooo confused.

Is a 12 week scan in theory done at 10 weeks since conception??

Boggled my brain!

Thanks

10 (weeks) + 5 (days)

Weeks and days are counted from the 1st day of your last period but a dating scan may push you back or forward

Hope this helps xx

Ahhh that makes sense.

So 10+4 would be 10 weeks and 4 days.

So at the point most people start telling others, around 12 weeks, they're saying they're 12 weeks pregnant but probably only conceived 10 weeks prior??

That is correct, yes

They would have conceived 10 weeks ago but they would still count as 12 weeks pregnant.
