What due date do I go by? Date of LMP was September 9, resulting in a June 16 due date. Ovulation was September 29, resulting in a June 22 due date.<br><br>
Which do I use until I go to my midwife?

I used my ovulation date, as that's more accurate. My midwife and the peri both agreed that I was spot on. There have been no changes to my date.

I would say just split the difference for now <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">

Use your ovulation and count two weeks prior to establish an adjusted LMP date (so, Sept 16th if I counted right).<br><br>
That's what I did first pregnancy and it made things much easier than having to constantly correct or remind my midwife or the nurses. (I told my midwife what my actual LMP was, but since I'd been charting and knew exactly when I ovulated, she was fine with writing down an adjusted LMP.)<br><br>
If you know when you ovulated, go by that date, and simply adjust your LMP accordingly so everyone's on the same page. Otherwise your dates will be a week off, which is no big deal early on, but can be if you're in a situation where your caregivers are nervous about letting you go past your due date, or the baby appears to come early, etc.<br><br>
Congrats!

My O and AF dates never match up to the same EDD. I always go by ovulation date since it is more accurate, and just figure out my my new AF date based on it.

Ditto. Use your ovulation date. Otherwise, they'll think you're farther along than you really are, and that could cause problems if you go past your EDD or if you're measuring smaller than their LMP-based date, etc.<br><br>
I used to ovulate around CD21 or 23, so I always had to go by ovulation date. This time, thanks to Vitex, I ovulated around CD 15 or 16. Woohoo!

This one is nice. You can plug in all the info. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">

Well, I called and set up my first appointment. They did ask when my LMP was and I accidentally told them when it really was instead of the next week to compensate for my late O. I then told her I charted everything and that I have my O date and she said, 'oh, well, they will just use your LMP date anyway.' Is it worth discussing when I go? I don't go in until Nov. 17. I just want to know if I should be looking at Week 4 information or Week 5 information. Probably 4, cause that's true to O huh?

When you go in, tell them that you mistakenly gave the wrong date over the phone and give them the corrected one. And leave it at that -- you don't need to offer any explanation. Go by ovulation minus two weeks and look at that LMP date as day one when you're researching info on development, etc.<br><br>
So yes, look at Week 4 info for now. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"><br><br>
Good luck!

Yes, it is important to know when you ovulated vs. the LMP (which assumes ovulation at day 14 - something that only works for women with 'normal', 'regular' 28-day cycles). If you did not conceive for at least a week later and they don't correct it then you could be in for problems at the end of your pregnancy.<br><br>
A midwife will probably be more lenient but state law may prevent her from being able to continue care with you if you reach a certain week over and if you are in the hospital they will push for an induction. With 'late' babies every day counts, so the more accurate your official due date is the better.<br><br>
However you choose to handle it is of course up to you, but I would not be satisfied unless a correct edd was given based off ovulation.
