1st cycle, barely a period!

I just finished my first cycle of letrozole and took provera to induce a period because according to ovulation kits I ovulated 3 different days 🤔 (I have pcos so I'm assuming that threw it all off) ... I started my period 2 days after my last provera pill like normal but this cycle is so light compared to my last few! I usually use super plus tampons but I'm getting away with regulars and nothing at night! anyone else have your flow get lighter after taking letrozole??
