However with both my pregnancies the EDD by ultrasound was just 2 days ahead of LMP EDD so they just kept it based on LMP. With both pregnancies I have measured about 2weeks ahead so I'll get an ultrasound at 36 weeks. With DD I was induced the day before my EDD, not due to size but because of pelvic pain. Not sure what we'll do this time. </p> https://boards.hellobee.com/topic/est-due-date-off#post-230360 Sun, 22 Jul 2012 16:25:50 +0000 SleepyMonkey 230360@https://boards.hellobee.com/ <p>it does matter if you had long cycles...i ovulated 2+ weeks (day 31) after the "average" woman does, and when i told my doctor, she adjusted my due date to 2+ weeks after it was based on my LMP. </p> https://boards.hellobee.com/topic/est-due-date-off#post-230270 Sun, 22 Jul 2012 13:13:41 +0000 ladyfingers 230270@https://boards.hellobee.com/ <p>My doctor went by LMP and I didn't even bother explaining that I ovulated on day 20, not 14. So far all my ultrasounds have dated me roughly 4-5 days behind where I'm "supposed" to be, so I know I'm right ;) </p> https://boards.hellobee.com/topic/est-due-date-off#post-230254 Sun, 22 Jul 2012 12:57:47 +0000 oliviaoblivia 230254@https://boards.hellobee.com/ <p>My ultrasounds are a few days ahead of my LMP/Ovulation dates and that's what they are going with despite the fact that I know exactly when we conceived. </p> https://boards.hellobee.com/topic/est-due-date-off#post-230250 Sun, 22 Jul 2012 12:55:48 +0000 matador84 230250@https://boards.hellobee.com/ <p>I've noticed on different due date calendars some ask for how long your cycle was and others don't. One calendar (webmd) where I estimate LMP with # days in cycle says I'm 34 weeks tomorrow, but another calendar just where it asks me LMP says I'm closer to 35 weeks. Not that it's a big difference...but I guess when I'm this far along, I'm just ready! </p> https://boards.hellobee.com/topic/est-due-date-off#post-230242 Sun, 22 Jul 2012 12:46:52 +0000 winniebee 230242@https://boards.hellobee.com/ <p>Mine went by LMP but my ultrasounds all indicated that was right on (and I knew I ovulated on or about day 15 of my cycle that month which would have been a 28 day cycle for me). </p> https://boards.hellobee.com/topic/est-due-date-off#post-230172 Sun, 22 Jul 2012 11:11:36 +0000 leelee 230172@https://boards.hellobee.com/ <p>My DR just went off of my LMP date which always irritated me. I explained to her that my cycles are shorter than 28 days and that since I was charting I knew the exact date I ovulated. She didn't care however she just stuck by the LMP date even though all if my ultrasounds indicated that my date was correct. I even had to wait an extra week to get induced so i was 39 weeks according to my LMP date however 40 weeks according to O date. </p> https://boards.hellobee.com/topic/est-due-date-off#post-230138 Sun, 22 Jul 2012 10:20:08 +0000 matador84 230138@https://boards.hellobee.com/ <p>Here's another question...when you go for your first appointment and the doctor asks what the first day of your LMP was to EDD...does it matter if your cycles were 28+ days or more? Or does it not matter at all and just based off the LMP? At this point, I think they're just going by what the sono is measuring, but I need to remember to ask my dr. at my next appointment.</p> <p>I might slap someone if they say to me again "there's no way you'll last 5 more weeks!" or "wow, your due date must be way off!" because it's making me crazy! Did anyone else get a ton of this?? </p>
