Clomid, cd 5-9

Heather
Ladies, help! I have been taking Clomid cd 3-7 but this last time did 5-9. My period is either 2 days late or my cycle is longer than usual. (I tested several days ago and got a neg result) 
Has anyone ever had longer cycles with the cd 5-9  on Clomid?? Is this normal? Dr is pretty sure I ovulated. 
Tia!!
