Come to think of it, how do people even know what blood group they are? Is learning one’s blood group one of the things that proper grown-ups are just supposed to do automatically, like making a Will and voting in General Elections? Is this another being-an-adult fail on my part?

Knowing my blood group was important to me as I needed an injection of antibodies after every pregnancy to prevent stillbirth.

Oh I didn’t realise about not being able to donate blood 
I’m afraid so. I think they exclude donors with health conditions unless they are positively sure that their blood poses no risk to the recipients of donated blood. MS, like a host of other conditions, is not well enough understood to pass that test. Besides, we have enough problems of our own - alas! - without depleting our blood supply on purpose.
It is oddly upsetting - isn’t it? - to turn from a healthy, normal adult who gave blood cheerfully and without a second thought into some sort of twilight invalid who is better off keeping her potentially dicey blood to herself! Ah well, that’s life.

Haha! If it is then i fail too. But then I don’t think i ever got the memo about being all grown up and sh!t so I have been blissfully unadulting most of my life! 
I’m anaemic so i’ve never been able to give bloody anyway, have no idea what actual blood group I am other than its the standard most common one! Pfft, I AM left-handed tho so at least not completely boringly average! Lol
