How early can you tell?

I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> procedure on 11/15 (8 days ago). I took the trigger shot two days before that (10 days ago). I’ve been feeling nauseous the past couple of days but I don’t want to take a pregnancy test and get my hopes up if it’s too early (my period is scheduled to appear this Sunday or Monday).
