Surgery requires a period of healing and what you are experiencing sounds like it is in the normal range. You do need to be alert for signs of infection, especially if you develop a fever or notice a foul odor with the pus at the site. Some oozing and bleeding is common and usually stops without intervention excepting slight pressure with a clean gauze.
Your size will not be affected. If your penis seems small now it is probably because during recovery it is best not to have any type of erection and your body is taking care of itself until you heal. The only thing removed is foreskin and there is nothing that happens in the circumcision to cause any other disruption to function.
It takes a while for complete healing and all genital stimulation/sexual activity should be avoided for about six weeks.
Best wishes for a full and rapid recovery.
