Myo inositol & period?

Geneva

so i’m on day 5 of taking myo inositol for my pcos, and i started spotting today. not sure if it’s a period starting, or just spotting, but i guess my thoughts are :

a) i didn’t expect it to start working after only 5 days!!

b) i expected to ovulate first, then bleed

Has anyone else had a similar experience? maybe just a coincidence? (i track with ovusense and i know i haven’t ovulated yet)
