@Melithehoneybee:  Congrats!

To my knowledge, the most accurate way to determine EDD is by ovulation/conception date.

You likely ovulated around cycle day 14 to cycle day 21, based on an average luteal phase of 10-14 days and your average cycle length of 28-31 days (28-14 = 14, 31-10 = 21).

Ovulation on cycle day 14 (Dec 30) => EDD September 22nd

Ovulation on cycle day 21 => EDD September 29th

I’d go with your first US estimate of September 23rd.

Congrats again!! 🙂

I would trust your doctor. Go with the most recent EDD he gave you – the 15th. With early pregnancy, the baby’s measurements will constantly change – could have just hit a growth spurt, tech couldn’t have been very good, machine could have been old, baby could have been moving to much for good measurements, etc, etc. There are SOOOO many variables. Go with the most recent – september 15.

@Melithehoneybee:  It sucks because your EDD is just that–an estimated date. I was semi charting, and honestly my dates don’t add up. It means I would have conceived during my period, so I don’t know. I end up going by my original due date rather than what they gave me because, honestly, the longer you can tell people you’re pregnant, the better. I would go by September 23 in your case.

I have no advice but I can totally relate! According to when I ovulated I’m due June 23rd but doctors changed it to July 16th. I’m going with the furthest date out just in case it is closer to the date baby will arrive so I can decrease my chances of being induced. It really is just an estimate and baby will come when he/she is ready!

I would go with the last ultrasound- September 15th

You weren’t charting so you don’t know when you ovulated, so you don’t really know the date of conception other than backtracking from your ultrasound EDD.  They changed my due date by 3.5 weeks around 16 weeks and it was the same (off one day maybe) at 20 weeks for my second ultrasound.  8 weeks should be just as reliable as the earlier ones as far as dating goes though, so that’s why I’d go with your last ultrasound.

You’ll also have another ultrasound (at least) at 20 weeks and they will also make sure the EDD looks correct at that point.

@Melithehoneybee:  I agree with Banana’s that September 23 sounds like the most accurate due date. I could go over the math again but I’d be repeating what she said.
