Testing after an IUI

Ryan • mommy to niko
I was soooo tempted to test today. I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> done 9/27. I feel nothing. Im trying to be positive but i feel like i would just know if i was pregnant. Should i take a test tomorrow or wait until sunday which is what dr said? Period due Tuesday.
