Cramping 5 days post IUI

Mindy
Hi ladies, has anyone ever had INTENSE cramps that only lasted about 30 minutes after <a href="https://glowing.com/glow-fertility-program">IUI</a>? I had light cramping the day of and day after but got hit with some of the most intense pain I've ever felt this morning (5DPIUI). It only lasted about 30 minutes but seriously felt like contractions. Hoping this is perhaps a good sign? 🙏🏻
