IUI and Testing

Katie
I had an <a href="https://glowing.com/glow-fertility-program">IUI</a> done on 9/8 so my TWW is almost up. I am supposed to get my period on Sunday, but the paper work said I shouldn't test until 14 days after ovulation (which would be Monday- my positive surge day or Tuesday-the <a href="https://glowing.com/glow-fertility-program">IUI</a> day) to avoid false positives. Has anyone ever had an <a href="https://glowing.com/glow-fertility-program">IUI</a> done and tested? I would love some advice.
