Hi, did you have sex with each of them only once? Because having sex three days apart, while making a dramatic situation in your mind, might not actually be when you got pregnant, if you and Mr. Fertile had sex at other times.
Anyway, you had sex with a guy with a vasectomy, and you had sex with a fertile guy, and you got pregnant, and the lab test you did ruled out the guy with the vasectomy and ruled in the fertile guy. It all adds up. Do you know if the vasectomy guy ever got his sperm levels tested after the vasectomy? That would also back up the DNA test.
What part of this feels troublesome to you? Even if all the lab said was "it's not the vasectomy guy," that should be enough certainty, but in your case, the testing went further and said "it is the fertile guy." I assume you are willing to trust medical science in general, such as, when you peed on a stick you believed it, right? Why you are now so doubtful about medical science that you can't trust a test done in a top lab? (Especially when one of the parties had a vasectomy and so there really didn't seem to be a need to test?) It's not like you did the test at one of those fake so-called "labs" in Canada that is renowned for losing results and only testing for a few markers; the DDC is one of the two best labs in the world for this kind of testing. By Internet report, there have been a handful of times when someone was given an "exclusion" (they claim, by the DDC) who was really the dad, but I've never seen an Internet report of someone being said by the DDC to be the dad who was not. And the reason I say "by Internet report," is that you never know what happened in the cases people report. A guy who didn't want to be named the father might have gotten his buddy to go to the lab in his place, there might have been communication issues between the collecting lab and the DDC, the guy could have been a chimera, etc. And some people who report issues online are simply trolls making things up; we have had that here. You can't trust Internet reports to be accurate, the lab test is real and online gossip has a thousand bad motives.
Women let their anxieties focus on paternity all the time when it is not the real issue. If you can't stop the unrealistic fears, you might want to consider talking over what is really scaring you with a counselor. Find the real source of your worry, and your paternity fears can be seen for the false target that they are, and will fade away.
When a lab provides a service to people all over the world, they have to have the samples drawn by local labs and sent to them; this is not unusual (and imagine how astronomical the testing costs would be if they could not rely on local labs to do the blood draw! They would have to build intake labs in every city and town in the world.) Your only problem would be if you thought the place you went was an out-and-out scam. How much did they charge you? Did you tell them which guy you wanted to be the dad? (If not, it would be a lucky guess on their part if they were trying to scam you, for them to guess the guy you want.)
It shouldn't be hard to find out if "DNAforce" has a relationship with the DDC, either by reading their website or by phoning the DDC and asking. Get the DDC's phone number off its own website (not from the paperwork you received), and if there is any kind of identifying number on the chart, read that to them as well. Then just ask whether this is one of their approved collection sites. I believe you can also ask for a proof of the chain of custody of the samples for an added small fee.
Sheldon, I noticed you posting on a different thread that you still have doubts. Do you want to try to figure this out by the dates? My original answer to you, I asked if you were sure the eventful three days was in fact even the correct time period to have gotten pregnant, if you had continued to have sex with the second guy. Did you have an early ultrasound, like, in your seventh week or so? If you did, it might help to confirm or change your idea of when you conceived.
Ovulation test kits measure the rise in hormones that triggers ovulation, but they don't necessarily mean you are ovulating that day. In fact, they don't mean you are ovulating that day unless the hormones had risen a couple of days earlier. Was that the first rise, had you been testing the whole week?
You got an ultrasound at 12-13 weeks and they told you that you were a week "ahead of that date." Could you give actual dates, not just conclusions? Maybe we can parse this out and be sure of what you were told. Please do it like this:
First day of last period: (calendar date) ______________
Date of first ultrasound:_________________________
(Was it at your doctor's or a pregnancy center?)
Estimated due date that they told you from that ultrasound:____________
(not date they said you got pregnant, but the date they said baby was coming)
Date of second ultrasound (calendar date):_____________________
Was it at your doctor's?
Estimated due date they told you from that ultrasound:____________
(not "they told me I was a week ahead," but the estimated day they said the baby was coming, from the ultrasound evidence)
Could the second ultrasound have been later than week 12 or 13 of pregnancy? That might explain the difference from the first one. Also, had you been having sex with guy #2 before the time with the vasectomy guy, or just after? Were you trying to get pregnant (thus, the ovulation testing)?
