For some weird reason I O'ed on cd 8 this month (it's usually day 15 <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/shrug.gif" style="border:0px solid;" title="shrug">). I'll find out in about a week if our "together time" on day 4 is going to change our lives again <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/makebabe.gif" style="border:0px solid;" title="makeababy">:.<br><br>
In the mean time, I was wondering if an early O would translate into an early birth date. With all three of my children I went into labor naturally and they were all born at about 39 weeks. So if I did get pregnant this month, would it be likely that the child would be born about a week earlier? Does anyone know if they had an early or late O during a month when they got pregnant? And if so, when was the baby born in relation to the O?

A more accurate due date going by o date would be to add 9 months and subtract 1 week.

Or...All the due date calculators assume a 28 day cycle. So, subtract 14 days from your O and call that "the first day of your last period," then calculate from there.<br><br>
Most months you'lll get the same thing as PP suggestion, but some months (like when February gets involved) things get just a little different.

Thanks! Those are good suggestions. I hadn't thought about calculating the due date that way, but it makes sense.
