Periods, ovulation and clomid

I've looked all over the internet but can't seem to find an answer so I'm hoping someone on here might be able to help....I've started my first round of clomid and was told not to try as I had too many follicles. I ovulated but I have started my period less than a week after...I thought normal it is start approx 10-12 days after?? Any advice is appreciated
