Just curious. According to an online due date calculator, I'm now 9 weeks (gestational, if I go according to my last period starting Dec. 30) and it shows my due date as Oct. 5th. Are you all dating your pregs the same way, or by date of conception? I will very likely go earlier though, in September - my previous was nearly four weeks early!
How are you dating your pregnancy?
DH had gotten a little freaked out by the thermometers and charting so I stopped. I'm not able to pinpoint the date of conception though now so we're going with LMP. It's a step up from the last time when I hadn't had a period for 3 months before I got pregnant and everything was done by ultrasound only. I'm pretty sure they had the dates really off too and that DS was much younger than we thought.
My LMP is pretty much lined up with when I probably got pregnant (my husband returned home from a deployment on the 10th of Jan, according to my LMP I ovulated around the 14th) and Im pretty regular. Ive never tempted or charted but Im pretty good with knowing when Im ovulating even without tempting.
Using December 31st as my LMP it gives me a due date of October 6th. Only way Id change it is if the ultrasound shows something very different.
lol, I'm actually in the weird boat that my thermometer stopped working right around the time I must have ovulated! I didn't figure it out for a few days though, and so my chart is all screwy, and my dates are all off.
SOO...lol, I'm going by best guess of 'opportunity' plus cervix position and calling the day I first noticed a very closed tight cervix after a lot of ovulation-like CM as my conception date. Which puts me mid-October.
My cycles are always pretty long...and this cycle, I actually had spotting a few days before when I assume I ovulated...which would TOTALLY throw dates badly off if I used LMP. I think I'm safer guestimating the way I've done ;)
How do you know the conception date for sure? We did IUI at a clinic, with 2 insems on 2 consecutive mornings. Ovulation happened the evening between the insems, but how do I know for sure when the swimmers and the egg got together? Even the "experts" disagree. The fertility doc said Sept 30 EDD and the midwife said Oct 2, then changed it to Oct 1 to split the difference. :)
Anyway, I'd rather go with a later date and push back the possibility of inducing as much as possible. It's my first, so I'm assuming I'll be late.
LMP would give me a due date of October 5, charting gives October 19 or 20. My midwife is great, but she has protocols she has to follow, and can't use my chart to set my official due date. My last birth was at 37 weeks 3 days, so I doubt I would go "post dates" even using the LMP, but I didn't want to worry about it, so I elected to have an ultrasound. My official date is October 21.
I agree...but at the same time I feel it can be confusing to use a different yardstick than everyone else when measuring how far along I am. Is this a case of 'when in rome...'?
We're going by conception date; it drives me crazy that the doctors all want to count from LMP and add in those 2 extra weeks! I understand why it's done that way, but it just doesn't make any sense to say that we're 8 weeks pregnant when it's actually only been 6 weeks since ovulation!
