Should I take Clomid?

We have been TTC for over a year now, we have been to the Dr and had two blood ovulation tests done. I am not ovulating, and have irregular periods, so I have been taking progesterone to better time my periods. My Dr said the next step is Clomid.. I'm not sure I'm ready to take it, and I kind of want to know what others think of it and what you all suggest. Anything helps!
