TTC with pcos

Ty • 21, ttc baby #1
Okay so I was diagnosed with pcos May of this year.. In June my obgyn put me on metformin to help me ovulate and regulate my period which was successful up until now. I'm on cycle day 48 and now my obgyn wants to put me on birth control for 3-5 months. Idk what to think. I've been ttc for 2 years and I don't want to miss out on ttc for that long. Any advice on what i should do?
