Pregnant after IF

Due Date Calculations

Just wondering how ladies who have done ivf calculate their due date.  By LMP or is there a way to do it based on the day of ER or ET?? Thanks in advance!

Re: Due Date Calculations

  • My RE calculated ours based on the ER date.
    Me: 43 DH: 39 - AMA, DOR
    Mommy to Sami (IVF), Born 8.30.13
    Surprise non-assisted BFP - 12.29.2014, Beta 1 = 322, Beta 2 = 760
    EDD 9.7.2015

  • Our doctor does 38 weeks from ER/fertilization. (Because when 'regular' people calculate, it's 40 weeks from LMP, which is about 2 weeks before ovulation.) So far I've been almost always exactly on target using that 38 weeks trick.
    Married 6/08, TTC 7/09
    MC w/ D&C 3/11 ~ 9.5 weeks
    CP/MC 1/12 ~ 5 weeks
    2 IUI's w/ BFN
    IVF 6/12 ~ 8R, 0F ~ Rescue ISCI gave us 3dt of 2 (6 cell, 9+ cell)
    DS born ~ 3/3/13
    IVF 6/14 ~ Operation Sibling ~ 10R, 5F ~ 5dt of 1 Blast
    Beta 1: 1600+, Beta 2: 4588
    Everyone Welcome!

    Um, no.  My LMP was Aug 14th....over 2 months before my ER.  She used the same date my RE gave me based on ER.

  • I thought I was due on 12/12/12 or 12/11/12 according to the on line calculators from my last period and retrieval date but the OB said it was 12/8/12. She came on 12/15/12. So I think the on line calculators are more accurate.

    Your OB is better than mine then. She ignored my telling her my RE's predicted due date which was based on ER date and insisted on going by LMP which I felt was silly.

    Unless your LMP and ER were very close together, there would be a difference between the two dates.  If I go by LMP my EDD would be May 21st.  My actual due date is July 9th.  I think it would be pretty obvious pretty fast that the LMP isn't quiiiiite right. 

    ETA: That's 19 weeks pregnant versus 13 weeks pregnant

    With DS it was the case that LMP was close enough. The two due dates were just a day or two off. With this case I have not graduated yet and it will not work using LMP. It would be 26 days off at least. So it will be interesting to see if she listens to me and RE's predicted due date this time around.
