I've heard that terms can be different on Clomid, too--I didn't temp that cycle because I was travelling, so I don't know what it did to mine. I should say that my normal pattern of fertile cm was absolutely undetectable on Clomid--without the OPKs I would not have been able to figure out which day I o'd. I o'd 5 days after taking the last pill.
Hope this is helpful....
