Did 6 gonal-f shots today -- iui wed

I did 6 Gonal-f shots today. I went to the dr this morning and he said that everything is looking good, and he stated that i had 12 folicals and he will see me fri for another us, and to start the Crinone over the weekend and then go back mon morning for us and possibly do the insemination on wed... now i am hearing alot of comments about women being on the clomid and then having severe cramps after the iui... i was just wondering if it was the meds or ovaries that are the cause of the cramps...??? thank you in advance
