counting pregnancy

[dueaprilx]

Hi ladies im due april 16
But I dont get how pregnancy is counted.
if I count lmp to due date it adds up to 41 weeks.

Funny question
From lmp to due date is it counted weeks 0-40 being 38 weeks from due date being around conception.

Orrrr is it week 1 to 40??
Is my u/s/sono guy wrong? With due date?.
Pls educate me.

thank you

You might be right about guilt.  A lot of women who write in to this community have two dates so close together that it takes careful analysis to try to decide if the answer can even be known, but a surprisingly large second group is more like you, they really do have their answer in the dates, but are still panicking.  I've come to think that this happens because they behaved against their values and now are ashamed, or feeling like "the piper must be paid" and their actions might come back to bite them.

If it gets bad, focus on dealing with the guilt, not the dates.  (Counting dates and 'what ifs' that are not justified by the calendar, don't take away guilt.)  Some women get relief from counseling, both to put what they did into perspective and to make plans that are constructive and about moving forward.  I sometimes tell the woman that if she decides from her guilty conscience never to cheat again, and to make her boyfriend the happiest father in the world, that is him getting something good out of the bad , maybe is even a trade a guy would make (of not knowing what went before, in exchange for having a loyal, doting partner for as long as they are together). You can atone by giving him that.  

Take care.  I think your ex was too early and your ultrasounds would show something totally different if he were the father.

Thanks anniebrooks I see you alot on here you never seem to be wrong you give good advice.

It could just be guilt like I know that my bf the father but that guilt is making me think otherwise.

No, probably not.  Nine days is a long time for sperm, I've heard up to 6 but not even reliably that long.

Hi thanks
Yea ex issue we had dtd on monday 14th july.

Do you think sperm would ov survived to my ovulation??.

[AnnieBrooke]

Your ultrasound says right on it that it is plus or minus 3 days.  I don't see many 6th-week ultrasounds that are even that far off.  How precise do you need it to be, are you trying to determine the father between two people who were very close together?

If you take the midpoint of the possible ovulation date and go up and down three days from  it, your possible conception range would be July 23 to 29 according to your ultrasound.

Hi anniebrook
Thank you for helping me.
I had a ultrasound early on the 27/8/2014.

Ultrasound says.
AuA 6w4d+/-0w3d edd aua 18/4/15

Yolk sac measured at 2.0mm.
Heartbeat was 86.96bpm.
They said the hb was probably low cause it might ov just started beating I dont know.

But I have a healthy pregnancy we are having a boy :).

2 questions??
How many days can a early ultrasound be off by??

And what is your opinion ov max days in july I could have concieved from?? To have this edd?

Thanks

If you are due April 16, you would have conceived around July 24, if the due date is accurate.  (At what point in your pregnancy were you given this estimated due date by the ultrasound tech?  If it was past your 12th week, there begins to be a margin for error of a week or more as time goes on.)

Also, some women ovulate earlier or later in their cycles compared to average.  If that is true of you (or if your cycles are irregular), your real first day of your last period might not match up to the projected or estimated first day of your last period given to you by the measurements from an ultrasound.  The ultrasound sees and measures the actual baby.  Your last period could have been five months earlier, and if the baby's measurements show it is only 6 weeks old, it doesn't matter if you didn't have a period in the interim, and it certainly doesn't mean you are six or seven months along.  When your actual last period was becomes much less important once you know the baby's measurements.
