Pcos , Metformin and Femera

Saniha
Hello, I have Pcos syndrome. Dr has given me Femera 2.5 mg along with metformin. Its cd12 dr had called me for appointment and I have 4 follicles which is 11, 10, 10 & 9mm.
Dr has called me again on cd 19, he says there is chance of follicles growing and I'm still on metformin. 
Has anyone faced the same thing. Do I still have chance of getting pregnant. 
Thank you.
