Brake bleeding

Hi I have a 1997 honda civic lx. I was trying to bleed the brakes and I stripped the front right brake caliper bleeder, so I bought a new brake caliper to replace it since the bleeder was stripped. I took off the old one, but couldnt get the new caliper until 2 days later, once I got the new caliper I put it in and tried to bleed it, nothing but air keeps coming out, ive repeated the process like 15 times. But still nothing but air. Could it be that when I removed the caliper and left hose open for 2 days, alot of air is in the system? Need help plz.
