Clomid if you already ovulate experience?

Sucess stories? I ovulate on my own..have been ttc now for over 6 months. Lake my bloodwork came back great, and progesterone levels b4 clomid good and now with are even higher. Did one round no success. On 2nd this month. My hubby hasn't gotten checked yet thought. But what are the chances of it being him? We had 3 kids together and trying for our 4th. I just turned 35 and my littlest just turned 2.
