It doesn't have to be exact, as long as you're within a few hours. Or if you want something that won't interfere with the IUD, maybe something progestin-only, like Cerazette? Or of course, you could choose to back up with barrier or behavioral methods like condoms or withdrawal, if those are options for you.
Definitely discuss with your doctor, as I am no expert.
