Today, my girlfriend of 8 years and I received our results from a DNA test. We're both very interested in history and ancestry, and wanted to see where in the world we both originated. It turns out we have the same father. FML

Fall
Dead leaves, the first cold of the season and an umbrella flipped inside out: fall, the season of grace.
Today, we got the results of our family's ancestry DNA tests. My father isn't related to me, but my grandfather is still my grandfather. Apparently grandma cheated on grandpa to get 'dad', and my mother cheated on 'dad' with my 'uncle' to get me. FML
Today, I got ancestry DNA tests for my parents and myself. The DNA testing company informed me that I'm a 50% match for my mother but I share no DNA with my father. Apparently, both my parents forgot that they used a sperm donor. This insignificant detail has slipped their minds for 35 years. FML
Today, my sister and I decided to do one of those online DNA tests just for fun. Our mom came in, saw all the stuff on the table, and lost her mind. She started bawling and apologizing. Apparently, neither one or neither of us actually belong to my dad. FML
Today, my husband presented me with a DNA test proving that our newborn daughter isn't his. Confused, I got her tested again. She's not a match to me either. FML
Today with a DNA test, I found out that my husband is my half brother. 30 years ago his father made a donation to the sperm bank my mother used, and I’m the result. To make matters worse, I’m pregnant. FML
Today, I took a DNA test and it turns out that the person who I thought was my dad is not my actual dad and my real dad is his best friend. FML
Today, talking to my boyfriend about each others families, we noticed we both had an aunt with the same name. After a while of trying to figure things out, we decide to call her. Turns out that we are long distance cousins. FML
Today, a DNA test proved that my 2-month-old daughter isn't mine. The real father is my girlfriend's husband, whom she married last year when she lied to me about going on a vacation. We've been together for three years and I never knew. FML
Today, my dad's will included a DNA test he did on me when I was 3, proving I’m not his son. I thought we had a great relationship, but apparently he secretly hated me all these years for mom cheating, and decided to embarrass me in front of our family, half of whom it turns out I’m not related to. FML
Today, the paternity test came back. It's like I suspected all along; my "son" is actually my half-brother. FML
Feel like sharing it with the other FML users?
Thanks, your FML was submitted, and will appear in the moderation queue soon!

I would do a second test. Maybe some cross contamination of your samples happened.

First I would check pretty carefully to see if the information is accurate before making any decisions. Second, if it is true I would not freak out about the situation. The chances of there being an actual issue in possible children from both having the same father (if it’s true) are generally way overstated. Get expert advice if it’s actually true - not from family and friends.

Yikes. Sounds like a case GSA- genetic sexual attraction. It's up to you two to decide what to do, especially since there isn't even a tiny chance of children. Look at laws for your area, etc.

Unfortunately that's not how it works. Cross contamination with DNA wouldn't make half of the be the same, and if it did it would be obvious because the chances are 0 that they got the same exact genes from their father

If you look at the little symbol next to OP's name you can see she is also a woman. That's why they can't have children.

Two women cannot have children together.

Saying that a brother and a sister (which is not the case here) can have a child is sick. And against the law.

If you two really love each other, i say screw it and get married if you want. Maybe not make any kids for fear of increased chance of defects, but there is always adoption and the choice is up to you. Like others said, do a second test first though, but in the end, you only just found out and that shouldn’t have to stop you

Legally, they can't get married or adopt. They're too genetically cloae.
PenguinPal3017 19
The government doesn't know about it, at least it sounds that way.
befuddled455 9
they can't have kids anyway due to the fact that the OP is also a woman

They can get married of nobody says anything

I think the best unwritten part of the FML is knowing that at some point, one of them got the impulse to compare parentage, like they perhaps suspected something was up.
joeyl1990 28
Yea I feel like that is the only way this FML could be true because at least the ancestory dna test I did they just told you where your DNA says you're from in the world.
PenguinPal3017 19
I think it tells you about people related to you who also did the test.

And now I guess it makes more sense when you look back at the family gatherings, where both you and your partner called the same man "dad"..

If the OP & his sister (including 1/2 siblings) live in the United States, all 50 states classify marriage, sexual intercourse, and/or cohabitation as illegal. Every state, except Rhode Island, has penalties that range from up to $100,000.00 and prison time. In 4 states, the penalty is life imprisonment.

I find it weird you know every state BUT Rhode Island has those laws.
Ashamed_Sister 60
It's "OP and her sister".
TaysDarkLust 11
Well... I mean, you made it this far, and clearly one of you didn't know your father, so you weren't raised together. I...don't really see anything wrong with it? It's not like you're adoptive siblings or something, you didn't know about the other person hahaha. I'd just keep it to myself and not let it affect me tbh. Don't throw away an eight year relationship over something like that just because you now know.
GhostFox 34
I'm rather certain that OP is also a woman, given their name in this post. Also, in some locations it would in fact be illegal for them to remain a couple with knowledge that they are half siblings. Which means they need to find that out, because punishment depends on location.
