What is the correct procedure?

I didn't have definite knowledge. My backcourt count was at 4 (I think, can't remember off the top of my head) when the player crossed midcourt. Then she dribbled into the frontcourt and was not guarded closely. My co-official blew the whistle after he noticed the clock, but the ball had been in the frontcourt for 3 or 4 seconds. It was one of those gyms where we only had one clock and it was behind me.
