How many sick days do you take?

I’m just wondering because I’m feeling anxious about this but can’t face going in and trying to function normally with the paranoia and impending migraine. I left early Monday, made it through the day Tuesday feeling extremely nauseous and weak, was off yesterday (Wednesday) and here we are on Thursday. I usually push myself to go in and take 1 day off every month which still isn’t ideal. I’ve only been at the job for 4 months and my monthly time off is noticeable.

Does anyone here take sick days for their PMDD? Do you stop doing other activities? Like I just can’t workout this week or do anything that requires patience of any kind. Just curious if anyone has done flexible work schedules, is there a way around this?
