I don't know my blood type

If you are unaware of your blood type you can be forgiven.... consult someone who will know like a doctor, your mum, a mosquito? 

Who doesn't know their allergies though?!?!!  Take the same advice as finding out your blood type....unless you have an allergy to mosquitoes that you are unaware of.... in that case, fingers crossed you find the answer before you have to hit up one of the little suckers!

Seriously though, if you don't know, leave this option blank until you do know, this could be darn helpful one day
