Hey there how old do you need to be to get an obortion?

Country. From a medical perspective there is no minimum age. Whether its via medication or by procedure, the more important critieria is to check with your country's laws regarding this. They may have age minimum's or other restrictions that I'm not aware of.
How old are you? The younger you are the more you should consider this. What are your circumstances? Children should not carry a pregnancy to term. Go for help immediately and involve your parents if you can.
