It doesn’t really matter in the grand scheme of things, but my curiosity has been peaked. I wonder if pregnancy can cause something like this and if it will be temporary or permanent.

lol even if this is the height of your curiosity it hasn’t been “peaked” at.

If nothing else hopefully the OP learned the difference between piqued and peaked

I had had a few strange "mistaken identity" moments in my town before, and so after that I used LinkedIn to track down my doppelganger. Got in touch and had a pleasant lunch with her (we were both graduates of the same grad program). I wanted to make sure that we knew each other so we could avoid any odd mixup consequences. We had lots of identical resume characteristics and, based on genealogy, her family and mine had branched off from each other about 200 years before. So she actually was a very distant cousin.

Same exact grad program and resume? Sounds sus. I’d contact the school as a recruiter and find out for sure.

PP. Lol. She was for real and not impersonating me. No concerns. By resume I meant...same undergrad major at different schools, same MBA, same industry (we worked at competitors), etc. I'd had some other experiences where people thought I was her or saw her name and thought of me. But she was not trying to steal my identity. In fact, she was the longer-term local with greater career success. We are still connected on LinkedIn and if it ever comes up now we can say that we're distant cousins and people like that kind of true, easy explanation. Even though there's 200 years of divergence.

Welll... it seems there w as a mistake. Gently, I might really wonder if my bio dad was who my mother says he is

Your blood type doesn’t randomly change. It is genetic. It stays the same throughout your life like your eye color.

Eye color can change. mine has - faded. Not uncommon just as hair loses melanin

Well your eye color definitely changes throughout life and not just from cataracts. Babies often have blueish or violet eye colors that turn hazel. And hazel eyed people’s eye colors change with their mood - if normally brownish they turn amber or green when they get mad or if normally green they turn blue when they get upset.

They can change from a lighter color to a darker color in infants and toddlers because babies do not produce much melanin when they’re first born. That’s why a lot of babies are born with blue eyes that later turn brown (for example). In those babies, it’s not really changing though because their eyes were always going to be brown based on their genetics. Brown is always their actual eye color that their genetics coded for. Once you have your final eye color, it does not truly change (unless you have some sort of medical condition). It’s simply an optical illusion.

What I meant is that they’re not going to drastically randomly change to a different color in adults (without a medical condition). They’re still going to be the same color that your genotype has determined. Brown eyes aren’t going to turn blue, blue eyes aren’t going to turn brown, etc. A lighter or darker shade of brown is still brown, a lighter or darker shade of blue is still blue, etc.

It’s the same thing for blood type. Type A isn’t going to change to type O, type O isn’t going to change to type AB, etc. Your genotype (AA, AO, OO, AB, etc.) has determined what your blood type is, and (under normal circumstances) it’s going to stay the same throughout your life.

This is why I’m always confused when another mom gets upset that her kid’s eyes have changed from blue to brown or green to brown. I’m Hispanic, and this is a big thing in our community. A lot want their kids and grandkids to have “colored” (blue or green) eyes. Your kid’s eyes were going to be brown no matter what. They just appeared a lighter color when they were little because their melanin production hadn’t kicked in yet. You can’t convince them of that though. 😅

The test from Amazon is the same type of test that they use in labs to determine a patient’s blood type BTW. It’s similar to hospitals and doctor’s offices often using cheap pregnancy tests to determine if a patient is pregnant.

It’s always a good idea to look at the reviews before purchasing anything online. I received the actual blood type test as shown, and it was accurate for me. As long as someone follows the instructions correctly, it should be accurate for them too. Unfortunately, there are a lot of people that do not follow directions.

I used this test a couple of years ago and thought my test was invalid at first because I had no reaction/agglutination in any of the circles. It turned out that I was reading the result wrong. I’m O- so there was supposed to be no reaction in any of the circles. It’s only invalid if there IS a reaction in the control circle. My husband saved the day by taking a look at it. I felt like such a moron.

It’s probably pregnancy brain for the OP because the grammar and spelling is otherwise good. I personally lose every shred of intelligence and forget basic things that I previously knew when pregnant. It’s different for everyone, though.

Right? I was wondering that too…

I had a one time emergency transfusion a few years ago and my blood type was tested during that time and I thought i heard them test the 2 units of blood to confirm blood type before giving them.
