TWW first cycle Metformin question

Mrs

Hey ladies I'm in the TWW and it's my first cycle on Metformin (1000mg a day). I've been really lax with tracking this month but I'm thinking I ovulated 10/04 (major ewcm with small red string of blood). So giving at least 14 days for luteal phase I'm assuming I'd be due for af tomorrow. I don't have most of my usual indicators (spotting, headaches, sore bbs, etc). I'll be testing this weekend but wanted to compare my symptoms to what yall have seen to see what's "normal" so to speak for this medication around AF.

What symptoms did yall notice your first cycle with Metformin? Or really any cycle?
