1st Trigger shot!!!

Amber • 30 years old. We have one daughter, born on 2/10/14. TTC #2 since December 2014. Finally pregnant with #2 due 12/4/17!
Just used my first trigger shot!!!!! Doctor told me to have sex yesterday (we did), skip today, and have sex tomorrow & Saturday. And if we want Sunday. First time doing trigger shot with TI. Was on femara for CD 3-7. Also on injectable blood thinners and a bunch of other vitamins. 
Anyone have luck with trigger shot and timed intercourse? 
Follicle scan was yesterday (CD12) and I only had 1 follicle and it measured at 18mm. So triggered today (CD13), he think I'll ovulate Friday night so I have to make sure we BD then!!
