Trigger shot question

Katie • Stay at home mommy as of 6/30/16!!!
Ok ladies
I'm going to do the trigger shot tonight for <a href="https://glowing.com/glow-fertility-program">iui</a> on Tuesday am! Dr said have no sex last night and sex of the day you trigger. No sex the day after to help with the sperm count! Hubs has good sperm.
Question do I do the shot tonight and then have sex or sex before then shot?? Please help!!!!
