3rd Trimester

when is my due date?

I have a million questions now that I'm very close to meeting my little one... Right now I'm confused as to when I'm ACTUALLY forty weeks. Based on the first date of my last period, I'm due October 11. Based on the date of conception I'm due October 12. But, after my first ultrasound when I was maybe 12 weeks the doctors changed it to the 20 due to his size. I'm only concerned as to when I'll reach 42 weeks so I know when it's really time to get him out if he doesn't come on his own. Has this happened to anyone and which date should I consider his due date??

  • I'm not exactly sure what that means...
  • That sounds like a question for your OB. 
  • Your due date is the one that your doctor gives you in the first trimester. After that, all period tracking and ovulation charts are no longer accurate EDD predictors.

    It's ok.  She doesn't fully know what it means either.

  • It wasn't my doctor that did the ultrasound then, which may be why I'm questioning it. My doctor sent me to the hospital to have it done, and I changed doctors shortly after that and she has just gone by what they said at the hospital. I haven't had one in my new doctors office yet. I'm just anxious I suppose.

    The person who did your ultrasound I am assuming is a trained US tech.  If your doctor didn't trust the information that was provided they would have discussed this and any modifications with you.  

    Honestly... we aren't got to make you any less anxious.  Please talk to your OB.  I just when through a L&D educational with my OB practice and they stated what they would be doing at each of the various weeks.

    Yep - talk to your doctor.  Your official due date will be in your record.  As an FYI the only ultrasound they use for dating (and changing due dates) for the most part is an early dating scan at 6 or 7 weeks and the due date is usually only changed if growth is off +/- one week.  I was told this is the only scan that is accurate for estimating a due date.  By 12 weeks all babies grow differently.  Also, it's common to go past 40 weeks with your first and very few babies arrive on the due date - it's an estimate of 40 weeks - unless you have IUI or IVF you don't know when you conceived - when you ovulate and when you conceive are two different things.

    To give you an example with my first my LMP "due date" was 5/17.  He was a few days ahead on a 6 week growth scan but not a full week.  By 12 weeks and several scans after that - the "tech" gave me 5/15, 5/12, 5/7, and 5/2.  It was explained to me by my doctor this is just a date that aligns to average growth - meaning my son was something like 85% for his 5/17 due date, but had he been 50th percentile for growth his due date would have been one of these other dates.  It meant nothing.  He came 5/23 (40 weeks 6 days).  Your doctor will know when to get him out, he'll likely come on his own when he's ready before 42 weeks. 

     
  • If you're worried about when you'll be 42 weeks for eviction purposes, ask what date your doctor has on record. Sounds like they are going by the later date which isn't a bad thing because they aren't going to induce too early based on erroneous dates. On the other hand, it you really think they have the wrong date and are concerned about "actually" being 43 weeks or something, talk to you doctor and ask for a BPP and/or NST to make sure you are still ok to wait.

    What do you mean conception date? Were you charting (ie. BBT) and know when you ovulated? If not ignore that date.

  • Forgive me if I'm missing something. Did you get your 18-20 week ultrasound? My Dr was unsure what my due date was so when I went for my Nuchal Translucency ultrasound they officially gave me my due date. Then when I had my 18 week ultrasound they compared the two. The tech said they wouldn't change my due date unless there was a large growth difference. So my Dr is going by what they said.

    So I would go by what the hospital said was your due date. Then if you had any other ultrasounds (which it sounds like you haven't) you could kind of compare. Like others said it could be a week off but should be close. I would always trust the tech vs the Dr. I love my Dr but she said the machines at her office aren't as good as they are at a lab or hospital.

    Lastly are your measurements on target? I know those can be off but if you're measuring on target or only a week big that should make you feel better. Sorry long post!
