Cramping long after AF?

Marlene • My wife and I have been ttc for almost 2 yrs now 1 of which we were doing ourselves. Now we are going the iui route.
I had my first IUI on the 1st took clomid and tigger shot, but got AF the 15th. Is it normal for me to still be cramping? They have been coming and going since the IUI! As anyone has had this happen too?
