Clomid advice!!!

Vi

This month i was advised to start Clomid without my period. So let's call Sunday CD1. I started taking Clomid 100mg CD2. I'm now on CD4 and after cramping all yesterday and worrying it was a side effect of the higher dose I've just come on my period!!!! Am i now totally out, I'm not sure what this means for this cycle?! I have still got 3 sets of tablets to take because I take them at night!

Advice please?!
