Thanks for the query. Clomiphene
helps in ovulation induction
Minor side effects like pain abdomen, blurring of vision etc can be seen with clomiphene.
But usually they will subside soon without need of medication.
As you are having persistent pain, better to rule out rare but serious side effect like ovarian hyperstimulation syndrome
So, consult your gynecologist once and go for ultrasound
Ultrasound helps in ruling out the possibility of hyperstimulation and also helps in monitoring the follicular growth.
By follicular study
you can track the ovulation and can plan intercourse around that period.
This will increase the possibility of pregnancy.
