Who is most likely the father?

[HeidiSunshyne]

I had unprotected sex on the 19th of June which was the last day of my period...the 1st day was the 14th...on Aug 12th I found out I was pregnant..the ultra sound read 8 wks 3 days.
I had unprotected sex with my boyfriend frequently there after...according to my ovulation schedule I ovulated June 29th...Which guy is most likely the father?

[HeidiSunshyne]

Yes...we live together. .so...alot

If the only sex you are trying to rule out is June 19, and you are confident you ovulated around the 29th, the sex on the 19th would have been too early to have gotten you pregnant.

Im actually just going by the ovulation schedule...I always thought that my period and the days right after were safe days...but I got confused by my ultra sound reflecting 8 wks...

[HeidiSunshyne]

Are ultra sounds acurate?...

[AnnieBrooke]

The days after your period are definitely not safe days.  But it still doesn't sound like you had sex late enough with the other guy for it to have given you a pregnancy around June 29.  Ultrasounds are accurate in the early weeks of pregnancy, can get less accurate as time goes by.  What might be the problem is that your understanding of the doctor's terminology sounds inaccurate, if you were worried about being told "8 weeks."  The doctor's count begins on the first day of your last period, or if he is looking at an ultrasound, the computed first day of your last period based on the baby's size.  It doesn't begin on the date of conception.  If you were to have asked the doctor "Does that mean I conceived 8 weeks 3 days ago?" he would have said, "No, about 6 weeks 3 days ago."

Thank u so much!!!....

Here is something I post a lot when it sounds like women think that the "weeks pregnant" given to them by a doctor means the same thing as the number of weeks since conception.  Hope it helps.
___________________

If a doctor, nurse, or any medical person says you're 8 weeks "pregnant", it is not a figure that counts back to conception but to two weeks before conception, to the first day of your last period.  All medical counts of pregnancy (the number like 6 weeks 3 days or 11 weeks 4 days) begin on the first day of the last period you had before getting pregnant.  If a doctor says to a woman, "Congratulations, you are 8 weeks pregnant!" he means 8 weeks since her last period began and about 6 weeks since conception.  

The count is done this way because especially in the days before ultrasounds, the last period was the only signal a woman had regarding her reproductive cycle.  The date of the last period, and its blood, is noticeable and ovulation is later, hidden, and unknown.  So they would begin the pregnancy count with that day (even though the doctor knew the woman was not pregnant then -- she was having a period!)  And they still do today.  All medical textbooks, computer-generated counts, and language used by doctors and nurses use that count (it's called "Gestational Age") even today when modern technology helps to pinpoint the conception date more accurately.  That is why pregnancy, which takes 38 weeks from conception to full term, is still counted as being 40 weeks long.  They add a spare two weeks at the front to be able to calibrate the count to the presumed first day of the last period.

So does this mean if I had concieved on June 19th  the ultra sound would have placed me even further along?

[HeidiSunshyne]

I mean because of the size of the fetus

[AnnieBrooke]

Correct.  If you conceived on June 19, when you had an ultrasound on August 12 the doctor would not have said you were "8 weeks 3 days pregnant."

My bf and I have been 2gether 2 yrs and I never got pregnant till the time period of the 1 time I ever cheated...wow...I hope this works out right.. .

[AnnieBrooke]

If you're brooding over having cheated, be aware of what you're worrying about.  A lot of ladies write in on this forum obsessing over their dates and unable to let their fear the wrong guy is the dad go, even when the dates don't suggest it.  What they are really looking for is to get past their guilt about cheating.  If that is what is really troubling you, don't let it settle on brooding over the dates.  Deal with the real thing that's bugging you.

[HeidiSunshyne]

I do feel bad about that...but up until you explained what u did...The dates matched up more with the June 19th date...and considering the fact I had never gotten pregnant b4 with my bf...there is def sum concern...I just want it to be his baby ..thats all

Thank you for responding❤

[AnnieBrooke]

Hi, what does "frequently there after" refer to, after June 19?

[HeidiSunshyne]

Yes...
