Am I having a serious complication after chin filler or is it just a bruise?

Hi! I had a chin filler injected a week ago. The doctor I have chose was very popular in my city and known to be professional. The filler I chose is the one that certified in USA and Europe. However on the next day I have mention a bruise on my chin. I have been putting creams on it for bruises but it doesn't seem to go away. Can someone please tell me if it's just a bruise and it will go away or if it's something serious? I am very scared and worried.
