Clomid question..late ovulation?

WorthyOfLove

This is my first cycle on clomid..I'm on cd 12 and nothing yet as far as opks go...before clomid I've gotten +opks..on cd 12 and 13... (I ovulate..maybe....my progesterone was very low so it's weak ovulation)

Is it common to ovulate later than usual on clomid?...the opks have lately been having only the one control line...not even a faint test line..
