Pcos & regular periods??

Vanu
Hi glow members, my doctor thinks that I might have borderline pcos, and  she has put me on metformin 750mg once a day. But I have always had regular periods, and I have never missed a period (very regular 28-30 day cycle) in the last 16 years!! I had a chemical pg in september so this time the cycle was 35 days. 
My question is, can you have pcos and still get regular periods?
