    Conception
    Hello I recently when to the doctors and the sonogram says I am 5 weeks. My last period was November 12. So according to that I should be 7 weeks. My problem is I had unprotected sex with my ex November 4. Could it possibly be his child? I was in the hospital November 22 and 24 and both time I went the took a urine sample and they were negative. I need help on an approximate conception date so I know my boyfriend is the father.

    It would be hard to identify exactly which date you conceived in the November as the sonogram only gives a generalised estimate based on size and other measurements, your best bet would be to wait until the child is born for a dna test or for your next sonogram to see if your dates change again as I got two different dates from mine

    Agreed, the sonogram is only a estimated guess at the number of weeks based on the size, but since babies develop slightly at different rates, there is no exact.

    The doctors estimates are also based on info you provide.


    So yes there will be no way to tell exactly until the child is born and a DNA test is done.

    Also why were you at the hospital those two days and why did you have a blood test done ?

    Dating from your last period gives you a gestational age, which runs 37 to 42 weeks for a term pregnancy with 40 weeks being given as an approximate due date. The sonogram gives you a fertilzational age, which tends to be closer to when you conceived since most women are not actually pregnant in the first week or two with gestational age. This is why you have a two week difference.

    While it's possible that you might have conceived from the sex on the 4th, it is not the most likely time since it was soon before your period. Given that the sex with your ex was just before a period was due, you had your period (assuming it came on time and was normal for you), and the sonogram results of 5 weeks, it is more likely that you conceived later in November. Additional peace of mind can come from any further sonograms if they do not alter the dating of the pregnancy.

    As the others have said, to be sure, you can have DNA testing done once baby is born.

    I agree with the other responders, it is hard to figure out the specific date of conception unless you are actively trying to conceive and write down every time you have intercourse. With the information you have try the Date of Conception Calculator on BabyMed.com. That's where I get all my information on pregnancy (have infertility problems).
