Pregnancy calendar ... is it accurate?

Question

For some reason, I thought it would be cool to have my next kid's birthday to be 7/7/07.

I tried the pregnancy calculator and it said that we had to conceive on October 14,2006 to have the birthdate I mentioned.

Unfortunately, I forcasted that my wife will have her peak ovulation day on October 8 which is 6 days off of the target conception date.

Which leads me to the original question .. for those of you who did this pregnancy calendar (which is about 266 days i think of birth after conception) is it pin point accurate? Or could I have a possible margin of error of +6 more days that I need. Please note that my wife will deliver though caesarian method so I could have the birthdate more or less around the target date I want.

I guess the folow up question is could you tell me if you gave actual birth after projected due date?Or before.

Thank you (p.s. I hope you don't find me selfish with this exact date thing ... when I know others may even have a hard time conceiving)

Answer 1

i think its +7or-7 days after due date...there can be instances when a pregnancyis longer than 40 weeks!

Answer 2

Unfortuinately...conceiving and giving birth are not exact sciences. Even if you could actually conceive on that date....your wife could be early or late to deliver. Ask the thousands of couples that tried to have millenium babies by conceiving on 4/19/99.

Thos calendars work by assuming every woman is a text book that ovulates 14 days before her period and carries the pregnancy for exactly 40 weeks.

You know how that goes........

Answer 3

you will conceive when the egg is ripest . . and deliver that baby when it is ready to see the world . . there is no given science to hit it on a certain day . . the only sure fire way to hit that date (if she doesn't go into labor before hand) is to schedule a c-section on that date

Answer 4

its about 90 % true
