Could Siphene Cause Ovarian Cyst?

hi i was on siphene 50 mg from day 3 to day 7.Before the prescription for siphene my follicular study was normal on day 2 but after taking siphene when i went bac for my follicular study on day 8 n was told to cancel the iui treatment as a huge cyst had occured. I wonder if it was due to siphene but once again im prescribed to take it this month(although they asked me to take just half by braking it) but i am yet afraid if the cysts develop again.Pl help
