Am I Ovulating?

Mari

(First cycle of clomid) For the past 2 days I have had really bad cramps with somewhat of a burning sensation in the pelvic area (both sides) also my lower abdomen feels bloated and heavy. Is this side effects from clomid or am I ovulation. Im on Cd17. Took clomid cd 5-9. Ive been testing since cd 11, all test have been negative. Anyone experienced this?
