Earring piercing hole bleeding help?

I got my ears pierced a long time ago when I was about 6,(I'm 17 now) and I used to wear earrings all the time but within the past year or two I stopped because I played sports and I always had to take them out and I never put them back in. I recently ordered a pair of cool earrings with bronze and nickel posts. I put them in yesterday and my ear almost immediately became sore and kind of itchy but I figured I just wasn't used to having earrings in so I kept them in all day and even overnight. The next morning I took them off just to clean them and my pierced ear holes were bloody. I soaked the earrings in a special cleaning solution and I also cleaned my ears of dirt and blood. Can anyone tell me what was the issue? I really love these earrings and want to put them back in but I don't want my ears to bleed again or make it infected. Any solutions?
