Paternity

I am eight weeks and three days along, according to my first ultra sound. I've had a steady boyfriend for 3 months now, but I was sexually assaulted on, May 4th. He knows about it, along with everyone else. But I was wondering what the chances are that my boyfriend would not be the father. I wake up crying because I'm dreaming about it and I can't even imagine what I would do. The first day of my last period was, April 29th and it ended, May 4th. My average cycle is 22-24 days. A paternity test is, +$1,200.00, but I can't go the whole pregnancy not knowing. The last ultra sound I had was done when I was six weeks and a day and the attack happened exactly six weeks to that day.

ps -- Be very leery of any prenatal DNA test that claims to identify paternity but only costs $1200.  There are a lot of bad reports of results that were wrong from so-called labs that pretty much just rip women off.  I'd recommend the DDC or Ravgen.  I assume you are prosecuting your rapist?  One thing to ask for is that he pay for a prenatal DNA test.

Sounds like you got pregnant on May 16.  If a doctor, nurse, or any medical person says you're 6 weeks "pregnant", it is not a figure that counts back to conception but to two weeks before conception.  All medical counts of pregnancy (the number like 6 weeks 1 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 6 weeks pregnant!" he means about 4 weeks since conception.  

The count is done this way because it calibrates to the day when the average woman's last period would have come before she got pregnant.  The period is a big, obvious signal, and has historically been used to begin the count of pregnancy weeks.  This doesn't mean the doctor thinks the woman is pregnant on day 1 of her cycle, he knows she isn't, she was having a period!  But that is why pregnancy, which takes 38 weeks, is counted as being 40 weeks long.  They add a spare two weeks at the front to be able to calibrate the count to the average first day of the last period.

Sometimes a woman's GA count (the weeks 'pregnant') given to her by a doctor does not align perfectly with when the first day of her last period really was. This is because a lot of women don't ovulate neatly two weeks after the first day of their last period.  The ultrasound sees and measures the actual embryo, so even if a woman gets a GA count that doesn't line up with her real period, she should date the conception as being the GA count less two weeks.  On the day the doc told you that you were 6 weeks 1 day 'along' or 'pregnant,' he was saying your embryo measured about what an embryo measures that had been conceived 4 weeks 1 days ago.

The only way this would not be true is if he said to you "You're 8 weeks 1 day GA, which means you're 6 weeks 1 day since conception."  But if you two were not using the exact word "conception" and talking about the difference between a GA and a conception date, he or she would have simply been using the medical way of counting the weeks of pregnancy, and saying your conception was around May 16.  Did he or she know about the assault and that you needed precision in dating conception?

The way to check all of this is to find out from the doctor when your due date is based on the measurements from the ultrasound.  From an estimated due date, you can compute an estimated conception date, and there is no confusion about what "weeks pregnant" means and whether the doctor is using the usual medical terminology or not.  

If you did get pregnant on May 16, you would not be pregnant from the person who assaulted you.  Sperm lasts perhaps five or six days in your system, not two weeks.

What was the date of the ultrasound?  I can't get the 8 weeks 3 days at the beginning of your post to add up to the same thing as May 4, it comes out more like May 2.

And how do you know your last ultrasound was done when you were 6 weeks 1 day, was that from the app also, or did the ultrasound tech measure the baby and say that was your GA?

Hi, beka, if your last sentence is correct, you were not impregnated by the rape.  Could you post your estimated due date?  The "weeks pregnant" given by a doctor don't begin at the date of conception.

Im more than positive you can get a paternity test for free after you give birth. I know I wouldn't want to wait until then but that's the easiest and cheapest way.
