Talk to Gynecologist on Spotting After Exercise

hey I'm 25 Yr old, married female. I have PCOS. last Yr I lost some weight and had my cycles regular. since January this Yr I'm again facing irregular cycles. my last sept scan showed bilateral bulky ovaries measuring 10-12 ml and the scan I got in June showed 15-16 ml bulky ovaries. I also did UPT, I was not pregnant. I have not had my periods since April now. I got my day 2 profile in April and it was normal. I was advised inositol supplement and I've just started taking them again as I started working out to loose weight and reverse my pcos. this time I'm facing mild red/pink discharge after workout. I'm worried what could be the reason. I do have mild brown discharge the day before my periods start always but this time my period ain't coming and I have this pinkish brown discharge after workout. please guide me thankyou.
