Confused by PCOS

Hi I’m new on here. Been on yasmin for years bar coming off to have my kids. Took it mainly for my skin. PCOS was queried a few years back but hormone profile and scan normal. Anyway have come off yasmin again 5 years after last baby. Skin is oily but no acne. I’ve been losing a lot of hair and my hair thinner. Still confused about PCOS. GP done bloods and all normal. Periods regular just oily skin and hair thinner. Lots of info mention signs of PCOS. GP did not check testosterone as other bloods were good. Anyone else suffer the oily skin or hair thinning and loss. Any advice greatly appreciated
