Is this normal? I got a piercing and...?

I got a second piercing for both ears on December 18. Im supposed to have them in for 8 weeks, So I will be taking them out in 4 days. Today I decided to change up my earrings on the newly pierced hole. so I took out the posts (kinda hard to do) and I put in the heart earrings (which are not heavy). I noticed that the actual pierced hole is very small compared to the first pierced hole i had (I had the first one since i was a baby) when i tried to take the earings out, on of the ears it hurt very badly, and it felt like the skin was still very tight, i dicovered this crust - like material around the pierced hole, and there was alittle blood. Does this mean I have an ear infection? Why is the piercing site still sore when It had a month to heal?!?!?
