Suggest Ways To Manage Cramps After Taking Ovidrel

I am undergoing fertility intervention, I took climid with no side effects and then took Ovidrel (to help ovulation) as directed by my doctor. Within the hour I had bad cramps. Just wondering if the Ovidrel triggered ovulation right away. Generally it should take a day or two. I have IUI scheduled tomorrow but just wondering if I am missing my ovulation window now. Of course offices are closed so I can not call.
