I wouldn't start clomid until you know for sure it is AF. You really need to get a Beta HCG & U/s done to see what is going on. Are you sure you aren't pg?

If not, can you get a prescription for Primulot from your GP or whomever you are in the care of to bring on AF? That way you know you have had AF for sure and then can start clomid. (I did Clomid for 6 months but didn't need Primulot to bring on AF)
