normal clomid side effects?

Daisy
It's now 6 days since I last took clomid. I took 100mg day 3-7 and this is my second round. I have had a headache every single day and tiredness I cannot describe. It doesn't matter if I get 10 hours sleep, I'm still tired. I can't function or do the most simply of tasks. Is this normal? I didn't have it 1st time around
