Getting frustrated...

So my period is supposed to start by Tuesday. Last week I had weird one sided cramping. And I have had slight spotting. So I am thinking this month is not it. But am hoping it is.... My husband is so frustrated that I'm not pregnant. He doesn't understand how we aren't yet. We have been trying for over a year and a half now. I am calling the doctor tomorrow to ask to be put on Clomid if I do start my cycle. That was the next step. But I have heard such positive things about the procedure that flushes out your Fallopian tubes that I want to try that. I'm hoping my doctor will listen and be understanding of what I want and need. Any advice or thoughts would be great. Baby dust to everyone.
