Blood type

I didn't know till I was pregnant because they told me to carry around a card with my blood type and information about me where ever I go incase of an accident. It had my blood type on it. O- I was 22 when I found out.

I'm still not sure what my blood type is. Everytime I send it to the lab they give me a different answer.

In my country your blood type is written on your driver’s license so if any accident occurs they can just check your license instead of doing a test or waiting for you to gain consciousness
