What happens if the i got a bruise then hit that same spot again? will it be damaged more?

Yes: If the injury is recent, put a cold compress to limit bleeding in the tissue. After a couple of days, using warm compresses may facilitate the clearance of hematoma. You may see color changes in the skin and that is a part of the healing process. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol or weed.
