Vaginal bleeding, 5 days post BBL, is this normal?

I started my regular period on Dec 13 and ended on the 16th. I had my BBL on the 19. Today is the 24th and when I used the rr I saw a bit of brown discharge. The next time I saw light red blood and it hasn't gone away. This is exactly what my period does when it starts. Is this normal? I've been healing perfectly fine for the last 5 days. Could surgery start my period again after 1 week? Today is Saturday and my surgeons office is closed. I don't know if I should be concerned.
