There's this lab we did in Bio where you can prick your finger and examine the blood under a microscope. Also you can take the blood and mix it with certain chemicals that will change it if it's that certain type of blood. The easiest thing you could do is ask your parents what their blood type is. A and B are both dominate traits so if one of them has that type then you have that type also. If one has A and one has B then you are AB. If and only if they both have O do you have O. Otherwise O is recessive and cannot show up if a dominate trait is present as well.
I hope this helped and good luck!
