Length Of Menstrual Cycle And Delivering Early Late

SAR - September 15

i was told recently by a nurse (not a midwife) that they have found a correlation between the length of your menstrual cycle and whether you go into labour earlier or later than your due date (ie. longer cycle means you will be close to your EDD or past it, and shorter cycle means you'll go earlier). has anyone heard this before? have any of the mums out there found this to be true with their other babies?

 

Confused - September 15

I've never heard of that before, but it might explain why I've had a tendency to be past the estimated due date (with my last three, of four, I was about a week overdue). However, I'd like to know why I was nearly a month past my EDD with my first!!! What would the nurse say about that?

It makes sense to me. Most people think that you ovulate on day 15 of your cycle, but really your ovulation is always a set number of days before your next period. This time frame is called your luteal phase. Most doctors base you EDD on the first day of your last cycle a__suming you ovulated around day 15. But if you have something like a 35 day cycle, you probably ovulated much later than day 15, most luteal phases last 12-16 days. So the shorter your cycle, the earlier you would ovulate. For instance, I know of about a 2 day timeframe of when I ovulated. Based on my first day of last cycle, my EDD is 11/29, but if I calculate out 40 weeks from when I ovulated (since I ovulated on day 16-17 of my cycle), Then my EDD would actually be 12/2.

I have read that this is true. I personally have a shorter menstrual cycle (by about 4 days). I read that I should subtract 4 days from my EDD to get the real date....Who knows though!
