Help determining paternity :(

[DreamyTiger]

I am so anxious, upset and full of shame that I am in this situation :(. I am pregnant and cannot be 100% certain who the father is out of a potential 2. I wonder if anybody has any thoughts or insights?
partner A: sex happened 1st October when I was day 7 of my cycle. Period stopped 2 days before. It was a pull out method.
partner b: sex happened 5th October when I was day 11 of my cycle. It was fully unprotected (no pulling out)
my cycle lengths are variable, occasionally 26 days in length, but mostly averaging at 28/30 days.

I had a dating scan which puts me at 8 weeks exactly today. I have also done a noninvasive prenatal paternity test which excluded partner A. Everything points to it being partner B, which is the result I want. However I know there no way of being exactly sure until baby is here and the anxiety is killing me.
please help :(

I have also done a noninvasive prenatal paternity test which excluded partner A. how accurate is this?

I’d say everything (dates and pulling out/unprotected) points towards man B.

This is what I’m unsure about :(. They claim to be 100% accurate and I’ve phoned them twice since receiving the results and they are adamant that they are correct. However, I have read posts where people have been given the wrong results. I used AlphaBiolabs which is government accredited in the uk. I really don’t know :/

Not helpful really is this. You look worse here by being so judgey with this comment just as an FYI

OP - it seems like it's partner B

These things happen… men are useless…

so don’t be hard on yourself… I’d just enjoy the pregnancy and do a paternity later.

Do you really want a headache to be part of your life forever…

Probably 90% certain to be man B.

You need to be honest with man B though. Are you this stressed because you want to hide the possible uncertainty?

Everything points to B. Is B aware of A?

Why is the man useless?

Sorry I'm a bit on the older side and have no idea what a noninvasive paternity test is but if it has excluded partner A surely that means it is partner B? Also dates seem to make partner B much more likely.

What is this test? How does it work? Cant be DNA, so what does it do?

The dates etc do point to it being man B

Once you have your actual dating scan at 12 weeks and get an official due date then you can count back 38 weeks and that will give you an approx date of conception - that's your most accurate way of working out the dates but nothing is foolproof. Only DNA can tell you 100%.

8 weeks isn't accurate unfortunately as early scans can be out with their measurements, likewise LMP isn't an accurate way of dating a pregnancy for many women.

I just googled. It is dna, it tests the fetus' dna in mother's bloodstream.

Fascinating.

I haven't looked into it enough to see how reputable / accurate it is, but possibly it is.

Maybe somebody with a scientific / medical background will be able to confirm

Assuming you’re not married to one and having an affair with the other and these are just two casual sexual partners, you’ve don’t nothing wrong.

best thing to do is chat to both of them and explain you’ve done the test pointing towards B but you wanted to be open and honest until a proper paternity test could be done.

it may seem like a long time to wait but within
months you will have answers and as long as you let them know you’re got nothing left to eat you up with anxiety whilst you wait.

it will all be ok.

It's most likely to be 'partner' B's baby. Why would you have unprotected sex, let alone right before ovulation, if you didn't want to fall pregnant?

I’m not so sure dates from scans are particularly accurate especially since the two dates are so close together.

with my first I know with absolute certainty I didn’t conceive on my dates given. DH and I were ttc, tracking ovulation and he was working away for two weeks when I apparently conceived. I know with absolute certainty i conceived a week earlier than they said, and funnily enough she was born at “39 weeks” at 9.6lbs

OP I would agree it’s much more likely to be partner B but obviously can’t be completely certain without a DNA test after baby is born.

People do all sorts not thinking of their ovulation dates really. It's not usually first thing on someone's mind when they are in the throws of passion

It's almost certainly parter b. Unless the baby will come out a different colour or something assume it is parter b and do another test after birth to exclude a.
Get an std test

That’s right. It’s a blood sample from mother and a buccal swab from both mother and expected father. They are advertised as being highly accurate, but since doing the test I’ve found plenty accounts out there of people who have gotten the wrong result.
Definitely Would be great to hear from someone with specialist knowledge on this area!

Very likely to be partner B, probably wasn't ovulating with the first. But you can't be 100% sure so best to tell both the situation as you know it and to do a test after birth.

Ignore any negativity, you can't change it now and stressing won't be good for you. Just be honest and you'll know for sure before baby knows what's going on.

That's the date of conception, not sex. Sperm can live for 5 days in the body. So if there was sperm from partner A, it could still have been in OPs body and capable of fertilising an egg when she had sex with B. Scans are also +/- a week. So really short of a solid 4 weeks between partners it's almost impossible to say with certainty based on dates.

I agree, that's why I said the only way to know 100% is with DNA.

The 12 week scan is the more accurate if comparing it with LMP date and an 8 week scan date but still not foolproof.

Very unlikely to be man A. Remember you are around 2 weeks 'pregnant' at the time of conception.
