If clomid doesnt work, what is the next step?

JA`s Mommy👶💙
I took clomid 50mg & 100 for two rounds n nothing. My Dr said to go back n see him if I didn't conceive. But its so hard to make a appt with him since he can only see me the days I work. Im just curious what will he tell me or what will he give me?..
