what is a blood group - #24015

Raj

I am really confused about what is a blood group and how it works. A few weeks ago, I went to donate blood, and I thought I was doing a good thing, right? But then they told me I can't donate because my blood group is rare or something. Honestly, I had no idea what that even meant, and I feel like I should know this stuff. Like, what is a blood group anyway? Is it just about the type of blood we have, or does it have something to do with other health things? I started thinking about my family, and my mom always talks about how she’s got O positive, but I’m A negative. Is that normal? I kinda feel like I should understand this better, especially since I heard that emergencies and surgeries depend a lot on knowing someone’s blood group. Does it affect things like receiving blood or even pregnancy? I just really wanna wrap my head around what is a blood group and how it might impact me and the people I care about. Can someone break it down for me in simple terms?
