Clomid related...

So, I just got a call from my ob/gyn saying after 3 months of Clomid 50 mg, that it's not going to work for me. I don't understand. I was only on it for 3 months & only on the lowest dosage. I thought it was going to go up to 100 mg this month. I guess I was wrong 😞 She wants me to get an HSG test done. Have any of you had this test done? I'm scared. Is it painful?
