DDC NIPT does it ever get easier

I had my doubts about paternity I conceived in JUNE LMP 6/2 I have 28-30 cycles....
I had intercourse with partner A 6/14 6/17 partner B 6/19 4am(so 6/20?) and partner A 6/21 partner A finished all 3 times and partner b pulled out.....
I was sure it was partner A's till my first scans started dating me for most probable ovulation 6/20-6/21 and it freaked me out beyond words
I got partner B to do DDC's NIPT with me on 8/27 got my results 9/18 which excluded him I was beyond happy now two weeks later I want to trust my results but recent false positives from two other females online have made me question my test....
I contacted DDC and due to my uncertainty they offered to review my results and if any questionable circumstances arise they would retest but I don't think I can get partner B to redo it for me I hope that is not the case....
as you can imagine im in a relationship which was rocky at that time and I just can find the courage to tell my partner about my doubts I hope my results are accurate and that when I hold my baby in march that he will look like his father.... it feels like a reoccurring nightmare mentally I want to be happy and not stress about this mistake anymore but its hard ive met enough supportive ladies here also which help distract me and help me want to trust my results but id lie if at the end of the day i could say i didn't still worry.

"Conception date" when counting from an ultrasound (if the ultrasound is early enough in the pregnancy to be useful for this purpose) is the day the sperm meets the egg and it becomes an embryo.  An egg is only viable for 24-36 hours.  But sperm can hang around for 5 days waiting for the egg to make an appearance, it does not become non-viable as fast as an egg does.  This is why someone can have sex on January 1 and conceive on January 5 -- the ovulation in that case would be on the 4th or 5th, and the waiting sperm from January 1 fertilize the egg.  But it doesn't work the other way around.  If someone ovulates on January 1, she will only have 36 hours from that point, before her egg is not going to work any more if it hasn't been fertilized.

Hi
I have been following this post as I have been in a similar situation - although now have had my baby.
I slept with two men very close together. I only tested one in a prenatal parernity test (not my partner). I was sure this man was not father, the prenatal test was done with blood. I got a much wanted negative result.
I continued my pregnancy assuming my partner was the father. He had to be - the other man was a negative result. I have had my tests reviewed and been told countless times - these tests aren't wrong.
My baby was born - the moment I saw my baby I knew the test was wrong.
I retested with the other man (not my partner) after the baby had been born - the test this time with saliva swabs. The results came back negative again and the mother father and baby data matched exactly to the first test.
I am now left with a baby that looks NOTHING like my partner or anything like my first child - going by the tests they have the same father.
If you have not slept with anyone else then you know your test is wrong. I have researched this and it is possible the man is a chimera with two sets of dna (starts off as a twin and merges into one baby). But apparently this is rare - but I think otherwise. I would never of got into this mess and had tests done if I knew there was a potential for error.
But once a man hears it's a negative dna he walks away because we are led to believe these tests are never wrong. But they can be.
I get comments all the time on how my children look so different, nothing alike, how my last child looks nothing like my partner! My first child he can't deny at all - they are so similar. He honestly does not look like my last child though - nothing. I am so sure he would test negative too - however this is not something I can even attempt as no one knows I cheated. For me there is not much I can do unless my partner or someone calls me out - I've embedded this child into our lives and have to live everyday worrying.
But if you need to prove a test is wrong, why not ask the mans parents to provide dna and do a grandparent test - this should show the result you need and then show the man he is the father.
I only wish my results and situation was different. And I know I sound crazy for not believing two negative results - but you know who your childs father is when you see them. My child is the image of the other man.
I'm sorry if I'm making people scared or worried. I just feel crazy and alone and want people to know they are not crazy for questioning results and hitting brick walls. I just wish people would believe us when we say the results are wrong instead of making us doubts ourselves!

Just because chimeras are rare does not mean they don't happen.  It's worth knowing how one tests when a chimera is suspected.  I read about a woman who was a chimera and she nearly lost custody of her child because her DNA test did not match the baby.  It took some good thinking on the part of the officials involved to get her a test from a different part of her body so it could be proven she was the biological parent of her own child.
Hi Ann you tested with DDC? also may I ask this other person was there any kind of protection? and thats a lot to take in girl but too me it seems you will need to get to the bottom of it to live in peace.... I understand your baby is part of your family now and that may continue to be once the case once all is revealed if your partner loves you he may find it in him to forgive you.... that chimera may be the factor it may not.. I have plently of family memners who look nothing like their siblings that doesnt mean they arent related... have you explained your concerns to the company u tested with? the second test was it with the same company? in my case there are two potentials so I wont know till i retest after birth in March.... have u ever thought of sending in a sample of your current partner for testing with your baby?

Hey girl I think we are all there! and get the waves of "what if's" we must be confident that we did what we could to help the situation..... I read the articles non stop about how they determine paternity and I remind myself that some of these results have to be accurate and I pray that ours are....

I really freak myself out at times but then I think about how I did get this test done and that there has to be a chance of truth to it and that's what helps me get through this......
I've also told myself that no matter the outcome my partner will be this childs father regardless even if we find out different later on..... Of course id be honest and hope that he would remain in the picture....

I was on what to expect with a few other ladies who were in our same predicament and both ended up having the baby and knew immediately who the father was (without the test) (biracial babies) we at least have something in our hand to help assure us of that moment when it comes...

Oh gosh thanks gor posting how ur results look like because once AGAIN I have been thinking about my results...as me and my future husband went together to my obgyn appointment and he was so happy seeing the ultrasound and i started thinking what if the results are wrong...but the blood results are so similar i doubt that they would find similarities if he was not the father...the SNPs would be sooo off right... :(....i just have convinced myself everything is accurate...but there are days when i am reminded that the results COULD be wrong. :'(

Maybe they were ready to post results that following day for you and realized they didn't have enough blood? but yes I would most def ask Chris about that date issue.

yes girl that little "what if" and the damn chances that these calculators and predictors that state it was the damn day of our mistake.... I was almost sure it was from the 17th because I remember my cervix was open and mid intercourse with my partner I even laughed and said maybe this time will be it, I  would just kill myself (not literally) if a damn pull out beat a whole finish lol.....
Yes girl that whole year we had tried prior to my weight loss I was tracking temping using ovulation sticks etc.... I was always a mid cycle ovulator cycle days 13-17 but this time supposedly I ovulated cd 20?  
I'm really hoping that ill be able to tell im hoping for the whitest little baby with orangey hair lol but I have dark hair so either way I might have to test.... unless he has his dads blue eyes then ill be more assured lol.

201603 yours makes sense since its only a day differrence mines says date opened 8|21. They sent me for a redraw 8|31 because it was not enough fetal dna.
Got my results on 9/09.
Thats the only thing that has me wondering why its shown like that.
No I do not plan on retesting if chris states that there is no problem on the review but i will ask about the date being shown differently?
But If once the baby is born I have doubts I will do a swab test .
Yes I agree. But looking at that conception can be from previous days so you could've had sex from 17 and concived on 20th .I think its just worry because of the guilt the date says we concieved day we were with the person we would not want too be the father , but I understand you completely it definitely is a scary thought . Did you ever track your periods or ovulation ??
