Reliable site to work out due dates and pregnancy weeks and days

[June2009]

Hiya!

I'm trying to find a reliable tool that tells me exactly how many weeks/days pregnant I am.
I've tried a few sites and they tend to vary from a few days sometimes.
The NHS one only says how many weeks, not days.
My brain has gone to mush and I'm getting confused

Here
Congratulations!

Awwww crumbs, that's not right... that one only gives weeks... still looking for you...
But I believe if you have a regular cycle, and know when your last period was, and when you ovulated, then you take the day of athe week of your last cycle, and go forward from there to find weeks and days...

For example, my last period was 12 May 2007, a Saturday. (DS born 13 Feb this year.) I have regular cycles and ovulated two weeks later, so (if this were happening this year, not last, IYKWIM) today (being Friday) I would have been 28 weeks and 6 days. Tomorrow being Saturday would flip me to 29 weeks, then Sunday would be 29+1.
Hope that helps!
