I am an ophthalmic photographer, not a doctor.
Getting your eye checked was the best move you could have made. Did you see an ophthalmologist or internist?
You got the spelling right on conjunctiva. The blood is liquid, thus incompressible, so there won't be any pressure issues. Assuming there is no tear or laceration to your conjunctiva, your eye should be as sealed against the environment as it is normally.
Some things to watch for after blunt trauma to the eye:
Check for obvious cuts and debris in the eye.
Are your eyelids opening and closing the same in both eyes?
Do your eyes track the same way, like following the end of a finger?
Are your pupils the same size, shape and responding the same way to light?
Is your vision the same in each eye?
Is there distortion, spots, double vision, light sensitivity, etc. in the injured eye?
Is your cornea clear?
Is the lens clear (visible through the pupil)?
Is there anything visible in the pupil? This would be like fibers or a crescent shape.
