Clomid Hangover?

So last cycle while taking clomid for the clomid challenge test I ovulated 3 days later than my "usual" date.  Now this cycle I got EWCM very early, and while my temps are very wacky I think I may have o'd on cd 13 - it works out for my travel schedule, but still it is a little weird.  Well, I guess I dont care as long as I end up with a healthy baby in the end :-)
