Intercourse then trigger?

Brittany

So my doctor just called and told me to trigger tonight at 9 but to have intercourse before I trigger. <a href="https://glowing.com/glow-fertility-program">IUI</a> is scheduled for Sunday morning (two days). Is this normal? Has anyone else been told to have intercourses two days before <a href="https://glowing.com/glow-fertility-program">IUI</a>? I thought it was recommended that the hubby refrain from evacuation 72 hours before. I am just a little confused. This will be our first <a href="https://glowing.com/glow-fertility-program">IUI</a> and I know success rates are low but I want to make sure I do everything possible to make it work.
