Help

I'm not sure you you can help me. I can't really afford to have a dna test.i had my July 21 2014. Shortly after I got pregnant. I didn't know when I got my period exactly so at my 12w4d ultrasound they dated me sep. 29th was lmp. Edd July 6 2015. I was with a guy on September 12 and 15 of 2014 and the other guy all the time. I don't think the other guy is the dad. What do you think?

I think that by the time the baby is here you could probably put together the $200 or $300 that a DNA test would cost.  Not that your dates suggest you need to do one, but your anxiety level suggests you will need to be sure.

Thanks. I told him I cheated today. But didn't tell him that it could be the other mans baby. He never asked. It makes me feel better alittle. My concern is do I do a dna test? I can't afford it. What's the chance it is the other guy.

[AnnieBrooke]

The ultrasound dated conception as being somewhere between October 6 through 20.  I think I would not worry about things that happened in mid-September.

[Newnew888]

I'm guessing. I don't know when my period was. The ultra sound dated it. I wish I knew.

[AnnieBrooke]

You mean, before your last period?  Then much less of a chance.

[Newnew888]

Actually the 15 and 19. Sorry

[Newnew888]

So I think my date is wrong:( but I'm not sure. What about being with mr. Wrong on sep 25 or 26.  What's the chance then???

[AnnieBrooke]

For various reasons, babies sometimes come early and sometimes come late.  It does not change when they are conceived.

[Newnew888]

One more Q. If I had my baby early would that mean my dates are wrong?

[AnnieBrooke]

I did not mean to imply that I thought you were brooding excessively now, I am just reacting to a lot of women who have written in on the site who do wonder, often, if the baby is their boyfriend's, and it drives them crazy.  If you think you would do this, get a DNA test with the guy you are trying to rule out, and since your dates really indicate it is not him you could do it with a drugstore test.  (I'd suggest a lab certified by the courts if it seemed like your dates were suggestive that there is a controversy.)

[AnnieBrooke]

The likely range of conception that is from October 6 through 20th.  This definitely does not stretch back to September 12 or 15. But if you are going to brood over the question forever, get a DNA test when the baby is born.

[Newnew888]

You are pretty sure right. I don't want to hurt the man I love and that does everything for my daughter and soon to be son:)

[Newnew888]

Well I'm going to trust that it's the man I'm with. Unless I feel the need to afterwards. I don't think my ultra sound should be that far off:)

[AnnieBrooke]

Thing to do, if it is bugging you, is to have a DNA test done with Mr. Wrong after the baby is born, one of those drugstore tests.  That way you can put your worries out of your mind.  And in the meantime, resolve to make the guy you are with the happiest dad in the world forever.  That means, take to heart that you made a mistake and you will never do it again.

I also had a vaginal ultra sound does that make it more accurate? And my 21 week ultra sound I just had the said baby measured to be due July 4. Which is 2 days off. So I have nothing to worry about. I just don't want to tell hom. He's so excited

[Newnew888]

That's a relief! I love the man I'm with. I messed up and didn't want to tell him. So no need to mess things up with him and get a dna test

[AnnieBrooke]

Once you have had an ultrasound that measures the embryo, it doesn't matter if your last period was a year ago.  The ultrasound measures the embryo and goes back in time two weeks to assign a computed first day of the last period.  But the measurement is based on the size of the actual embryo.  Mr. September is out of the picture.

[Newnew888]

Sorry I had my daughter July 21,4014.  I don't remember having a period that late. But I'm not saying I didn't because I don't know. I just had a baby not long ago and was always tired then lol

[AnnieBrooke]

"i had my July 21 2014" means what, your period?  Your baby?  

What they gave you at your last ultrasound was the following --

First day of last menstrual period:  September 29
Probable date of ovulation:  October 13
Possible dates of conception:  October 9 to 17
Due date:  July 6 (40 weeks)

If it was based on an ultrasound in your 12th week, add a margin for error of a week to those dates, giving you a range of conception that is from October 6 through 20th.  This does not stretch back to September 12 or 15.
