pregnancy due date using ovulation date

My first ultrasound measured what the calculators said.

July 12 was given to me at my 18 weeks 5 days ultrasound (using that due date). The last one given to me before that was July 7 (which was at 12 weeks 5 days using the July 12 due date or 13 weeks 3 days using the July 7 due date). Is it all too close to tell? I'm planning on having a DNA test anyways but for my own peace of mind I'd like some reassurance.

Do you mean due date changed according to us scan date and LMP date or during the pregnancy because baby grows fast? I am like dianaexoh and ovulated late so had my due date put back 2 weeks after first us scan. I have a friend who just had her due date pushed forward 3 days at 20 weeks because her baby is growing fast.

No. You didn't get pregnant in October.

Yep, I agree with Pam. Even though they date your pregnancy as 40 weeks from first day of LMP, we all have slightly different cycles, and ovulation times. If you have a 26 day cycle, that can change things a bit. The ultrasound is more accurate. Your Dr. would have let you know if he was worrying about measuring behind, and it sounds like all is just fine!!

I actually know my conception date (feb 2) since I was using ovulation tests. I didnt tell my dr and they gave me a due date from my ultrasound (oct 26). Just about a week ago I was curious as to how far off the due date/weeks was so I went to two online due date calculators using conception date and it gave me the exact same date of oct 26. Grant it that my baby probably wont get here that date but at least my weeks are pretty precise. I was shocked.

Has anyone had their date changed? Based on my LMP my due date should be 9/27 but the US I had today put me back to 10/6. I looked at my dates and although we avoided what should have been my ovulation week, we still managed to get pregnant. 12/21 - 12/27 LMP 1/7 proposed ovulation Relations 1/10, 1/14, 1/24 Missed period 1/21.

I went for an ultrasound on the 23th April 2013 and the gestational age of my baby was 13 weeks 2 days with a due date of 27 October. Am really confused because that puts my conception date at the 2nd of Feb. On the 13 June, i had another scan and the baby measured BPD =49.7, HC=170.4 and Ac= 147.2 Can someone pls help calculate when conception was likely and the accuracy of the ultrasound. I have been given a due date of 27th of October.

Most calculators will assume a 28-day cycle, whether you go by ovulation or LMP, so since you calculated by your ovulation date, the calculator probably just counted back 14 days to get the LMP date of November 11. If your cycles are irregular in length, you're definitely better off using your ovulation date to calculate due date.

we did have sex while I was ovulating and just for fun I tried a pregnancy due date calculator and using the first day of last cycle said I would already be 2 weeks pregnant. Just wondering how you can be pregnant 2 weeks before you ovulate and only 3 days after your period just ended. I tried multiple websites and they all the same thing. It just doesn't make sense to me or my husband.

If a woman has regular cycles there will be a 2 week gap between lmp and ovulation. The due date for you will be calculate by your LMP even if your conception date is known as that is the way it has been traditionally done. The traditional method assumes the two week gap or greater if the cycles are varied in length. (It is just easier to ask/know when your last Lmp was then to know when one ovulates). That is where the utility of the US measurments really shines.

So, I know for sure that I am pregnant, but I'm wondering which day I ovulated, so I can pinpoint my due date. I was using the Clear Blue digital OPK, and it says it's supposed to be positive two days in a row. Well, I started using the test on August 2nd, which was cycle day 10 for me. I didn't get a positive until August 12th, cycle day 20. (I'm breastfeeding my 14 month old so I ovulated late.) So, I only got the one positive on CD 20, and the next day it was negative.

so i figured i conceived on dec 6th. which would put my due date at the end of aug, beginning of sept. my dr said its the end of sept/beg of oct. it doesn't seem correct. 40 weeks from dec 6th is the beginning of sept. is my dr wrong? or am i nuts.

2 Can someone pls help calculate when conception was likely and the accuracy of the ultrasound. I have been given a due date of 27th of October.

My question is does the dr. based the due date on the last date of my period because at first she had told me that my due date was on sep. 24 but the last time I saw her she did an ultrasound and she said that my due date would be sep. 23 because I was not sure of my last period. Another question is, what happens if I go over my due date, lets say a week later. Does that mean I had concived my baby during the time I was not ovulating.

Yay we r due the same date. That's great to find a mommy due on the same date as mine. Where are you from I'm in Jersey.

Until you get an ultrasound, you can't know a due date with a lot of certainty, especially when you had a pause in your flow and then it began again (unless this always happens for you. Some women with bicornuate uteruses have that happen). However, it mostly sounds like the period on March 18 was your official last period before getting pregnant. For that date, here is what the conception calculator says.

Yes i wanted to make sure that it was the right due date cuz with that being said my last Period and due date gives my a ovulation date at the end of may 2012 the 26th baby was born feb 14 two days early and ultrasound was at 12 that's when they told my due date when was ovulation date? How early can u even ovulate..

My phone apps give me an due date the same as my doctor which would give me an ovulation date of July 14th but if I calculate my ovulation date from ultrasound due date that would give me an ovulation date of July 9th. Which would be an more accurate way to determine ovulation?

according to my Ultrasound and Ovulation date i'm due Dec 28. according to my last cycle date i'm due Christmas day. but we didn't find out gender... we are going for the surprise.

I went by LMP.
