Is it normal to not know your blood type?
Yep.Totally normal
Yes—lots of people don’t know their blood type. You usually only learn it if it comes up during blood donation, pregnancy, or medical care.
Totally normal. Unless you’ve donated blood or had a reason to be tested, your blood type may never have come up—and it’s not something most people need to keep track of day to day.
If it matters for medical care, clinicians can test or verify it rather than relying on your memory. You can ask your doctor or a blood donation service if you’re curious.
