Clomiphene citrate 100mg from 3rd day for 5 days any possibility for twins and conceiving? please answer

Twins possible: Medication that is used to make a woman ovulate such as clomiphene citrate and when used in the highest dose always carries the risk of resulting in a multiple gestation, that is twins and more.

Yes: most clomid (clomiphene) pregnancies do result in singleton gestations (1 baby), but have a mild increased risk of twins and much less so triples and beyond.
