If you are past your due date or have been with a previous LO...

then please share.

I've read that the estimated due date is based on a menstrual cycle of 28 days. Mine was typically 30-31 days which makes me wonder if my actual due date is a few days later than predicted.

Just curious how many others have had post-date babies with longer cycles?

I had a 28 day cycle when I got pg with DS, and I was induced at 40w3d.

28 day cycle and induced at 41 weeks.

I had regular cycles that averaged 28 days and I was induced at 41 weeks with my daughter.

I have read some things that suggest early ultrasound dating may have decreased the number of "postdates" babies, who actually just had their due date miscalculated.  But you are talking about a difference of just 2-3 days dating error, which is within the margin of error for ultrasound dating anyway.  Even ovulation charting has a margin of error of at least 1 day, so very few people ever know their due date down to the exact day.

I don't think you are truly post-dates until you hit 42 weeks anyway.  A due date is just an estimate.

I had clock work (28days) cycles and was 4 days late with DD.

I'm past due, but my cycle is about 35-45 days so I was expecting to go late.  What people fail to realize is that normal gestation period is actually 40-42 weeks...so you aren't technically late until you've reached 42 weeks.

My cycle always ranges between 28-35 days or so.  We used an OPK the month we got pregnant, I did cycle tracking prior to that, and we had an early ultrasound to date the pregnancy.  Soooo...my date should have been pretty accurate, but by my estimate it would have been 2 days later than my provider dated it.  

That said, I'm at 40w2d today and still pregnant.  By either calculation, baby is still going to be at least a little past the 40w dot.  Mind you, going over 40w doesn't mean going past term.

I had 28 day cycles before DS#1, my water broke at 41 weeks and he was born 41w1d.

This time I had 31 day cycles, got pregnant, miscarried, then got pregnant again without having a period... so I've got no idea how that will effect things.

My cycles are 35 days. Based on my LMP that would put me with a due date of 1/23 but because I know exactly when we went for it, and had a dating ultrasound at 6 weeks, my due date is 1/30.

I had a 30-35 day cycle, and was induced with DS at 41.5w.  However, I'm convinced that I had to be induced because he wouldn't descend because he has a big head, was faced the wrong way, and apparently I'm narrow in terms of my anatomy in that area.

I typically have long cycles (between 34-37 days) and spoke with my OB about it at my first appointment. My EDD would have been January 21 but due to my cycles, the doctor put it at January 28. And according to the ultrasounds that I have had, that's about correct.
