Cramping after IUI

I had two <a href="">IUI</a> this week ..... I was on clomid andestrogen  and a trigger shot .... I had three follicles on one side from 18mm to 22mm and two on the other side ... One was 32 mm and the other was 20mm ... I had my second <a href="">iui</a> today and I seem to have cramping ... Is this normal???
