Cramping 4 dpiui?

Hey ladies... I had my first IUI this past Sunday. No issues whatsoever following the procedure. Today I've been feeling kind of irritable and started having mild cramps this afternoon. I've also had an increase in CM. Anyone else ever experienced these symptoms? Again, this was my first IUI, so I have no experience whatsoever. I'd appreciate any stories you ladies are willing to share!! Thanks 😊
