I have had an IUD for 2 weeks, every day I have intense stomach pains for several hours

Good evening,

It can be normal to have cramps and pain following the insertion of an IUD. Acetaminophen or ibuprofen could be used if there are no contraindications to their use

However, since you are talking about intense pain for several hours, I suggest that you contact your doctor who performed the installation to make sure that everything is normal.

Also monitor your temperature (if fever), any variation in vaginal discharge or any variation in vaginal bleeding.
