Trigger shot!!!

Alyssa
This is my husband and my first cycle using a trigger shot and timed intercourse. My Dr. said to BD before the shot (same day) and then the evening of the shot between 9-12 pm, and every other day for 3 times. So we BDed this morning and I just have myself the shot now at 6pm. Do we BD again between 9-11 and then not BD tomorrow and BD on Tuesday? I'm confused...
