I had a iui done 4 days ago and now i'm cramping is it normal or should i be worried?

No: I suppose you mean intrauterine insemination. When you have sex the ejaculate pools in the posterir vaginal vault and only a few of the sperme swim up into the uterus. When the sperm is injected into the uterus, it isn't used to that so cramping will occur, but the little swimmers are persistent and will get through. Good luck

Expected: Some cramping after IUI procedure can be expected and should not be a cause you to worry unless you experience other symptoms. I am sure you are aware of the success rate of the procedure, which is low at 10-20 %, but lets keep the fingers crossed. Best of luck!.
